The spectral range is 400-1000nm, the wavelength resolution is better than 2.5nm, and up to 1200 spectral channels can be reached. The acquisition speed can reach 128FPS in the full spectrum, and the maximum after band selection is 3300Hz (support multi-region band selection). Brake fluid, also known as brake oil, is used to transfer pressure in the vehicle hydraulic brake system. Automotive brake fluid can be divided into alcohol brake fluid, mineral oil brake fluid and synthetic brake fluid. Alcohol brake fluid is made of refined castor oil and ethanol or n-butanol, which is cheap, but has poor high and low temperature performance. Mineral oil brake fluid is made of refined diesel distillate as base oil, adding viscosifier, antioxidant and anti-rust agent. It has good temperature adaptability, but it has swelling effect on natural rubber. The synthetic brake fluid is composed of ethylene glycol ether, diethylene glycol ether, triethylene glycol ether, water-soluble polyester, polyether, silicone oil, etc. as solvent, adding lubricant and additives. The operating temperature range is wide, and the corrosion effect on rubber and metal is small. Different brands of brake fluid have great differences in formula, price and quality. The quality of brake fluid is directly related to the driving safety of the vehicle, and the use of fake and shoddy brake fluid will lead to brake failure or brake failure due to the occurrence of high temperature air resistance and low temperature brake delay, resulting in safety accidents and injuries to vehicles and people. According to the sampling results of 47 enterprises in 2005 by the State Bureau of Quality and Technical Supervision, the qualified rate of brake fluid is only 45.9%, which has great safety risks. Brake fluid is a colorless and transparent liquid, and it is difficult to distinguish different brands of brake fluid from the appearance, and special analytical instruments are needed to identify it. At present, in addition to the OTC3890 brake oil analyzer of OTC Company in the United States, there is no equipment for the rapid detection of brake fluid parameters. Rapid identification of brake fluid is very important to ensure the safety of motor vehicles. Using vision-near-infrared spectroscopy to identify different brake fluid has the characteristics of rapid, non-destructive and low cost. In this study, the vision-near-infrared spectrum information of five brands of brake fluid between 400 and 1000 nm was obtained by spectrometers. Through principal component analysis, the cumulative confidence of the first six principal components reached 98.55%. Based on the first 6 principal component data of 225 samples, the identification model was established by stepwise discriminant analysis. The prediction results of 75 unknown samples showed that the prediction accuracy of the model was 94.67%, which realized the rapid and accurate identification of brake fluid brands by using near-infrared spectroscopy, and provided a new method for rapid identification of brake fluid.

In this study, a 400-1000nm hyperspectral camera was applied, and FS13, a product of Hangzhou Color Spectrum Technology Co., LTD., could be used for related research. The spectral range is 400-1000nm, the wavelength resolution is better than 2.5nm, and up to 1200 spectral channels can be reached. The acquisition speed can reach 128FPS in the full spectrum, and the maximum after band selection is 3300Hz (support multi-region band selection). mounting time is one of the important factors affecting cocoon quality. In the actual acquisition, usually the cocoon that is spinning silk and the hairy foot cocoon that has not pupated are collectively referred to as hairy foot cocoon. Generally, mature silkworms are cocooned from the first day of cocooning at 25℃ to the third or fourth day of cocooning, and then moult and pupate after 2~3 days. With the increasing of mounting time (3-7d), the number of cocoon layers and cocoon-layer ratio were increased by 2. According to the study, no cocoon was pupaed on the same day when the cocoons collected 48h after cocooning were cocooned. Cocoons collected 72h after cocooning were cocooned had a chrysalis rate of 26%. The pupaation rate of silkworm cocoons collected 96h after cocooning was 78%. The pupaation rate of cocoons collected 120h after cocooning was 100%. In the process of cocoon circulation and processing, the main harm of hairy foot cocoon is that the drying and folding is larger than normal cocoon, which affects the quality of cocoon and raw silk. Especially the cocoon which has not finished spinning will directly affect the filament length, cocoon layer ratio and silk yield. The pupa, tender pupa and normal pupa of hairy foot cocoon were easily suffocated after steaming, and the pupa shell of the tender pupa was easily broken in the dry, and the dirty juice or oil of the pupa polluted the cocoon layer and formed the next cocoon. According to statistics, the boarding rate of hairy foot cocoons in the same batch is 2~4% lower than that of normal cocoons, the relaxation rate is reduced by 4~6%, and the relaxation rate of severe steam heat is reduced by 10% or more. According to the experience data of the silk factory, the relaxation rate decreased by 1% or the boarding rate decreased by 1%, the corresponding nest fold increased by 3 to 4kg, the cost of raw silk will increase, and the quality of raw silk and the price of silk will be reduced. In this study, visible/near infrared spectroscopy was used to identify the hairy foot cocoon. The feature wavelength was extracted by continuous projection algorithm (SPA) and the model was established by PLS method, which provided the basis for rapid identification of hairy foot cocoon. In this study, visible/near infrared spectroscopy was used to identify hairy foot calluses. First, the baseline correction pretreatment method was used to eliminate the difference in the baseline of sample spectral data caused by different acquisition times, and then the principal component analysis (PCA) method was used to qualitatively analyze the hairy foot cocoon and mature cocoon. Then, a method for identifying hairy foot cocoon based on least square support vector machine (LS-SVM) algorithm was proposed. The continuous projection algorithm (SPA) was used to reduce the 601 spectral variables to 12, reducing the model variables by 98.00%. The identification accuracy of hairy foot cocoon by this model reaches 100%. The results show that the hairy foot cocoon can be detected by visible/near infrared spectroscopy.

SCI refers to the inclusion of specular reflected light mode, generally used for those who study the properties of the color itself without concern for the color attached to the surface gloss of the sample manufacturers, such as paint coating factories. SCE refers to the method that does not contain specular reflected light, which is generally suitable for those samples that are directly observed and require measurement results to be very close to the visual view, such as home appliance housings. In the SCE measurement mode, specular reflected light is excluded and only diffuse light is measured. The value thus measured is comparable to the color of the object as it appears to the observer. When SCI mode is used, specular reflected light is included in the measurement along with diffuse light. The value measured in this way is the overall objective color of the object, and has nothing to do with the surface conditions of the object. These criteria must be taken into account when we choose an instrument. Some instruments can also measure values in both SCE and SCI modes. Even if the object is made of the same material, the color will look different due to the difference in surface gloss. For example, when the surface of a smooth, bright blue sample is rubbed with sandpaper, why does the blue appear a little dimmer? When the elastic ball is thrown at the wall and bounces back, the Angle is the same. In the same way, because the light source produces light that is reflected back from the same Angle in different directions, we call it mirror reflected light, because the light is like being reflected back by the mirror. Light that is not reflected by specular reflection but scattered in all directions is called diffuse light. The sum of specular and diffuse light is what we call reflected light. On smooth, bright surfaces, specular light is stronger and diffuse light is weaker. On rough surfaces with low gloss, the opposite is true. When we look at a blue plastic object with a smooth surface at a specular reflection Angle, the object appears less blue because the specular reflection from the light source is added to the color of the object. Generally speaking, people ignore the reflection of specular light when looking at the color of objects. Therefore, when measuring such samples, in order to make the data look like the object, it is necessary to exclude specular reflected light and measure only diffuse light. The color of an object is different because of the amount of light reflected by the mirror we observe. We already know that because people only look at diffuse light, when the surface conditions of the object change, the color will appear different. However, since the material of the object itself is the same, the color of the object should not change. How can we get the color of the material itself? The content of specular reflected light and diffuse light is determined according to the surface of the object. But under certain conditions of material and color, the total amount of the two kinds of light is always the same. Thus, when the smooth blue plastic sample is roughened, the specular reflected light content decreases and the diffuse light content increases. This is why we need to measure the total reflected light (the sum of specular and diffuse light).

Hardware surface color is a variety of, but also through a variety of means of surface color treatment. Not only for the light color is beautiful, more is to achieve surface oxidation protection. The control of the color of the hardware surface has become an essential part of the production process of hardware products. Generally through some special methods to the hardware surface color deployment, such as spray painting processing, electroplating, surface polishing, corrosion processing, etc., are the deployment of hardware surface color. Through painting processing, you can avoid rust on the surface of the hardware, such as daily necessities, electrical enclosures, crafts, etc., need to be treated with surface color. Electroplating is also the most common metal processing of a processing technology, through modern technology to hardware surface plating, to ensure that products for a long time under the use of mildew does not occur embroidery, electroplating processing common screws, stamping parts, battery pieces, car parts, small accessories and so on. Surface polishing processing is generally more commonly used in daily necessities, through the surface burr treatment of hardware products, the sharp parts of the corners are thrown into a smooth surface, so that it will not cause harm to the human body in the process of use. In addition, the metal die-casting (die-casting is divided into cold pressing and hot pressing), stamping, sand, mold casting and other processes will also change the color of the hardware. Because the surface of hardware products is relatively rough, and some even have lines, therefore, in the color difference control, it is necessary to use a large-caliber color detection instrument to detect it, so as to detect the object color difference surface more evenly. The color difference detection of hardware materials can better judge the difference between materials, test samples and standard samples, remove unqualified products, and improve product quality. Due to the particularity of the hardware product itself, the precision requirement of color difference detection is not very high, and the color detection can be realized by using a general large-caliber color difference meter. CS-520 handheld color difference meter independently developed and produced by color spectrum can fully meet the detection needs of hardware surface color. It is a portable computer color difference meter designed by 45°/0° optical geometry structure, which is a large caliber instrument in the current domestic color difference meter, and has a high measurement accuracy. The color measurement results of the CS-520 handheld colorimeter simulate human eye observation, but the accuracy is several times higher than the human eye. The CS-520 hand-held colorimeter can effectively eliminate the error between human eye and colorimeter caused by sample surface pattern when judging the threshold of sample color tolerance. Therefore, CS-520 handheld color difference meter is widely used in color QC department. CS-520 handheld color difference meter can meet the plastic (Biqian, PFFT,PP working flower name 2 section, Eve particle and powder), color steel plate, paint, textile, fluorescent materials, denim medicine, medicine, food and other industries analysis and control the quality of the production process, to help enterprises control product color difference, improve product competitiveness, reduce enterprise losses, control production costs. Therefore, the CS-520 handheld color difference meter is the most suitable for color difference detection of hardware products.

Luster belongs to the visual perception of people on the one hand, the buyer in considering the value of the product, the luster of the product and the color have the same important status. Objects with a high gloss look like they can glow, and are not metal but have a metallic luster. The gloss of the surface of the object will be affected by many factors, such as: the smoothness after polishing, the thickness of the paint used, the brand, and the substrate of the object. Manufacturers will continue to introduce new designs according to the needs of buyers, such as: highly reflective car panels, high-end magazine covers, fashionable furniture in satin black and other products with gloss treatment to reach a greater extent to attract buyers' attention. Manufacturers in the production, to ensure that the gloss of the product is strictly carried out according to the standard, which requires the gloss meter to be used as a detection tool. The application scenario of gloss meter can make incoming material inspection, quality sampling inspection in production, and factory inspection. Ordinary gloss meter is only suitable for measuring flat products such as paper and tiles, but small objects or curved products such as buttons, thermos cups, wrenches are not suitable for measuring with ordinary gloss meter, which requires the use of microporous gloss meter to measure special irregular shape products. The microporous gloss meter CS-300S (measuring aperture: 2*3mm) can solve the gloss measurement of irregular samples, and is suitable for measuring the surface gloss of complex shapes on the measured surface such as mechanical parts, jewelry, crafts, plastic pipes, hardware decoration, test samples, etc. (Same applies to flat gloss measurement). Microporous gloss meter CS-300S measurement demonstration: 1. Start calibration 2. Sample measurement (sample fitting measuring aperture) 3. Click the Test button 4. Obtain a 60° gloss of the workpiece 【 Insert video 】 The operation process is not very simple If you need to evaluate the gloss of more angles, I recommend the multi-angle gloss meter CS-380, which supports the measurement of 20°, 60° and 85° 【 Insert CS-380 product introduction 】

Light reflectivity and gloss are two different concepts, there are many different differences between them, but there is a certain connection, in general, the higher the light reflectivity of the object the higher the gloss. When light is emitted from a medium to the interface of another medium, a part of the light returns to the original medium, so that the propagation direction of light has changed, this phenomenon is called light reflection, the ratio of reflected light and incident light, is the reflectivity. Gloss refers to the ability of the surface of the object to reflect the light from a certain Angle, and the main factors affecting gloss are the roughness of the surface of the object and the molecular structure of the object itself. We know that the reflectivity of different objects is also different, the reflectivity mainly depends on the nature of the object itself and the situation of the surface, as well as the wavelength and incidence Angle of the incident inductance wave, the range of reflectivity is less than or equal to 1, the use of reflectivity can judge the nature of the object. The reflectance formula is that when the beam is close to normal incidence (the Angle of incidence θ is about 0), the reflectance formula is R=(n1-n2)^2/ (n1 +n2)^2. Where n1 and n2 are the true refractive indices (that is, refractive indices relative to vacuum) of the two media respectively. Refractive index refers to the phenomenon that the Angle of light changes when it enters different media, and is characterized by sinθ1/sinθ2. θ1 and θ2 are the angles of incidence and refraction, respectively, that is, the Angle between the light and the normal. In general, the reflectivity of light on the critical plane is only related to the physical properties of the medium, the wavelength of the light, and the Angle of incidence. In the case of continuous change of refractive index of the medium, the reflectivity is also related to the thickness of the medium because of the interference effect of reflected light at different interfaces. Thus, we can design a coating with a specific thickness and a specific refractive index to obtain a coating with a large reflectivity or transmittance to a specific wavelength of light. The reflectivity is related to the refractive index of the two media, the incident Angle, the wavelength of the light, etc. The greater the incidence Angle, the stronger the reflected light. In the case of a certain medium and wavelength, when the incidence Angle is greater than a certain (critical) Angle, the reflected light is equal to the incident light, which is called total reflection. Fiber optic transmission takes advantage of this phenomenon. The gloss unit (GU) scale is linear, and each Angle of incidence has a different measuring range. 0-2000GU (20°), 0-1000GU (60°), 0-160GU (85°). % Reflectance compares the light energy sent and received with a gloss meter and expresses the full measured range of Angle incidence of the value in percentage, and the value is displayed as a percentage with respect to the selected Angle of incidence. Therefore, the light reflectance and gloss are not only different in the concept of light reflectance and gloss, but also in the calculation method is different, light reflectance is a percentage value, and gloss has GU units. The optical reflectance of the human eye can not be subjective and objective effective judgment, and the gloss can be judged by the human eye.

In our past cognition, the desktop spectrophotometer generally uses side measurement or upward measurement to measure non-transparent substances, and these two measurement modes also cover the color detection of all non-transparent substances.                                                                Side measurement                                         Upward measurement   So why is there a pattern of handstand measurements? This needs to start with the structure of the desktop spectrophotometer, a very important part of the instrument measurement is the integrating sphere, the integrating sphere of the desktop spectrophotometer is 152mm in diameter, and the interior is coated with a layer of white diffuse reflection material, the diffuse reflection coefficient of the diffuse reflection material is close to 1, and the sphere is close to an ideal sphere. In this way, after many reflections in the integrating sphere, the lighting source will form a uniform illuminance on the inner wall, which improves the measurement accuracy of the desktop spectrophotometer.                                                               Reflection test principle                                    Integrating sphere   To sum up, it is very important to ensure the cleanliness of the integrating ball. When the inside of the integrating sphere is polluted, the accuracy of the measurement data is bound to be affected. Especially like the textile and fabric industry, in the cutting process, there will be a lot of raw edges and fabric debris, if the side measurement or upward measurement is used, the fabric debris is very easy to fall into the integrating ball, and it is easy to stick to the inner wall of the integrating ball. Over time, the integrating sphere of the instrument is scrapped, which not only shortens the service life of the instrument, but more importantly, affects the accuracy of the instrument measurement. Fabric frills, scraps   For this kind of products, color spectrum technology proposed the inverted measurement mode, install a vertical bracket on the desktop spectrophotometer, and put the test port corresponding to the integrating ball down, no matter how the measurement, the fabric debris will not fall into the integrating ball, to ensure the cleanliness of the instrument. Vertical support back                          Vertical support front   Customized vertical stand for desktop spectrophotometer CS-820N/821N/826, to ensure the stability of the instrument upside down, movable damping handle, to ensure that the test port does not leak light during measurement, so that the instrument accurately evaluates the color of the product. Test port detail diagram                      Handstand measurement   In addition to the textile fabric industry, powder can also be measured in this way, welcome to consult us!

Gloss test principle Glossometer mainly measures the glossiness/reflectance of the surface of an object. The gloss is calculated by reflecting the incidence Angle of the light source back to the corresponding Angle receiver. The gloss unit is GU Generally divided into: single Angle: 60° measurement Multi-angle: 20°, 60°, 85° three-angle measurement What is light spot: Measuring the area of light emitted during the hole test, not measuring the hole size.   Roughness and gloss misunderstanding The difference between roughness and gloss   Surface roughness refers to the small spacing of the machined surface and the unevenness of the small peaks and valleys. The distance (wave distance) between the two peaks or two troughs is very small (below 1mm), and it belongs to the microscopic geometry error. The smaller the surface roughness, the smoother the surface.   Surface roughness and surface finish are the same concept, and surface finish is another name for surface roughness. There are corresponding comparison tables for surface finish and surface roughness.   Surface roughness meter Surface roughness measurement using roughness meter (size detection instrument) detection; The surface glossiness is the strength of the diffuse reflection of the object surface to the light, which can be measured by the surface glossiness. Surface gloss To the naked eye, the surface diffuse reflection is strong, it is closer to the mirror effect, then the gloss is high, on the contrary, the surface diffuse reflection is weak, then the gloss is low, so the gloss is also called mirror gloss.   Handheld gloss meter                                                   CS-300 single Angle gloss meter                                                            CS-300S microporous gloss meter                                                Test diameter 2*3mm                                                                                Test diameter 2*3mm   Gloss units and national standards   What is the unit of gloss? In China, our general saying is how much gloss is, for example, the gloss is 60 degrees, it can be understood as a gloss of 60GU or 60%. What does GU stand for? Gloss meter unit we call the Gloss unit, the international practice symbol is expressed as GU, is the acronym of gloss unit, according to the provisions of JIs standard, gloss unit can be written as a percentage sign or number, the domestic gloss meter generally measured range is 0~ 200GU~ 1000GU.   National standards for gloss: 一、gloss meter 20° reference standard: DIN-67530, ISO-2813, ASTM-D2457 GB 9754, GB 8807, ISO-8254, ASTM-D523, which is mainly used for high gloss ink, paint, paper, plastic, stone, light casting coated paper and so on.   二、gloss meter 60° reference standard: ISO-2813, DIN-6750, ASTM-D2457, ASTM-C584, ASTM-D523, GB 9754, GB 8807, GB 9966 It is mainly used for medium gloss coated paper, marble, ceramics, paint, ink, plastic and so on.   三、gloss meter 85° reference standard: ISO-2813, DIN-67530, ASTM-D523 GB9754 It is mainly used for camouflage coating, low gloss paint and so on.   Handheld gloss meter difference Gloss meter is generally distinguished by the test Angle, Spot size, range differentiation   产品型号 CS-380 CS-300 CS-300S   测量角度 20°、60°、85° 60° 60°   测量光斑（mm） 20°：10*10 60°：9*15 85°：5*38 60°：9*15 60°：2*3   测量量程 20°：0-2000GU60°：0-1000GU85°：0-160GU 60°：0-1000GU 60°：0-600GU   分辨率 0.1GU 0.1GU 0.1GU   测量模式 简单模式、标样与试样测量模式 简单模式、标样与试样测量模式 简单模式、标样与试样测量模式   测量重复精度 0-100GU:0.2GU100-2000GU:0.2%GU 0-100GU:0.2GU 100-2000GU:0.2%GU 0-100GU:0.2GU 100-600GU:0.2%GU   测量准确性 满足JJG 696一级工作光泽度仪要求 满足JJG 696一级工作光泽度仪要求 满足JJG 696一级工作光泽度仪要求   测量时间 小于1s 小于1s 小于1s   数据存储 可存储100条标样，10000条试样 可存储100条标样，10000条试样 可存储100条标样，10000条试样   尺寸（mm） 165*51*77（长*宽*高） 165*51*77（长*宽*高） 165*51*77（长*宽*高）   重量 约400g 约400g 约400g   语言 简体中文、英语 简体中文、英语 简体中文、英语   电池电量 3000mAh锂电池 3000mAh锂电池 3000mAh锂电池   接口 USB、蓝牙(可选) USB、蓝牙(可选) USB、蓝牙(可选)   上位机软件 包括 包括 包括   工作温度 0-40℃ 0-40℃ 0-40℃   湿度 小于85%，不结露 小于85%，不结露 小于85%，不结露   配件 5V/2A充电器、USB数据线、说明书、光盘、校正标准板、计量认证证书 5V/2A充电器、USB数据线、说明书、光盘、校正标准板、计量认证证书 5V/2A充电器、USB数据线、说明书、光盘、校正标准板  

Not every product looks so uniform and flat. Products with irregular shapes, as well as reflective and fluorescent products, also require color detection and control. This is a multi angle colorimeter that can perform more complex measurements as needed. In fact, multi angle color measurement colorimeters are mostly developed for color control of metal paint. We know that many products in industry are metal paint colors, and measuring colors with ordinary colorimeters is not accurate because of their high reflectivity. However, products such as automobiles, household appliances, and hardware have very high color requirements, so the development of multi angle color measurement colorimeters is also beyond doubt.   Many standards objectively describe the color measurement of multi angle colorimeters as the color measurement of the fastest flashing topcoat. Generally, the results of data analysis show that if you want to measure the color of metallic paint well, at least 3 observation angles are needed, and 5 are generally the best. To understand the color measurement of metallic paint, we need to be familiar with a keyword: adverse reflection angle. Adverse reflection angle refers to the observation angle measured from the mirror reflection direction of the light source in the same horizontal plane.   Usually, the formula for calculating color difference using the colorimeter we use is represented by data △ L *, a *, b *, or L *, C *, h *, with △ representing the total color difference. However, this is within the allowable range of color data differences. For the angles of adverse reflection angle and brightness/dark transition angle, they have already exceeded this range. Therefore, using this method to detect and analyze obvious results is unreliable. Therefore, scientists are allowed to develop multi angle color difference meters based on industrial needs and measurement ranges. This colorimeter brings groundbreaking benefits to products such as appliances and cars that have very strict color requirements and are difficult to measure.   The purpose of developing a multi angle colorimeter is to capture the complete trajectory of pigment color changes caused by light interference. Moreover, the entire measurement program is reliably used in industrial use, and the measurement is convenient, fast, and suitable for color detection and control in large-scale production. Therefore, the widespread use of multi angle color difference meters is reasonable and inevitable. It does not know how many manufacturers meet the needs of metal color detection.

You may have heard of shared products and services such as shared bicycles, shared umbrellesand shared bookstores, and even enjoyed such products and services. These are not surprising to you, but have you heard of "shared colors"?   It can be imagined that when the color can be shared, then it will become easy and simple for people to engage in the deployment and control of color. For manufacturers of all walks of life, the control of product color will be simple and convenient. "Sharing color" can be said to be a subversive initiative of precision instruments in color detection.   The appearance of Color difference treasure makes "sharing color" a reality. Today's color difference meter has developed into a more intelligent, digital and accurate color detection instrument after years of improvement and development. The sample color information measured by the color difference meter can be connected to a printer or computer through the instrument to realize real-time sharing of online color information. Provide more professional color solutions.   You can check the "View Shared color Library" in the "COLORMETER" APP, which is an open and shared color database uploaded by users. You can collect your favorite database, as usual work to find color reference use.   In addition to sharing colors, Chrominance has a variety of options for sharing colors: First, color Difference Treasure can share color information through the "ColorMeter" APP. Color information can be shared in the following five formats:   The second, color difference treasure can connect to the micro printer through the APP Bluetooth, print the sample color information, according to the color information Lab value, color difference, guide color matching, color management. From this point of view, the ColorMeter is more like a copy tool to read color information. By detecting and "grabbing" the color information of the sample, and then connecting to the printer to print the color information, it realizes color information sharing and communication.   Thirdly, the color difference treasure can also be connected to the computer through the USB port, through the computer can be more accurate to give the absolute value of two colors (L*, a*, b*), color difference data (dL*, da*, db*, dE*), according to the color difference range set by the software, automatically draw the "qualified/unqualified" conclusion. Store color data and various color representations such as data, reflectance curves, color difference maps, statistical trend maps, color blocks, etc. It also includes various color Indices: metachromatic index (MI), whiteness, yellowness, etc., which can realize online sharing of color information between PC terminals. According to the color information, the corresponding color solution is adopted to guide the control of product color difference.   To sum up, whether through APP, or connecting to a micro printer, or connecting to the PC end, the color difference meter can realize the sharing and sharing of color information, so that color information can be transmitted and communicated in time through paper or digital means, which is very intuitive and convenient. Colorimeter makes it possible to "share color", which is a great convenience for the staff who need color control, so that the color of the product can achieve "copy and paste", the color control of the product has become convenient and feasible, and the colorimeter has therefore been widely used in the control of product color in all walks of life.
