Recently, we get customer inquiry for measuring color of meat by spectrophotometer, today we will introduce how to measure and which instrument is suitable and why need to measure it.   1. Why need to measure the color of meat?   Color is one of the most important quality index for meat. The color of meat generally changes slightly with time, and consumers often associate the "appropriate" color of meat with the quality and freshness of the meat. For example: fresh tuna has a ruddy color, but this red color will decompose with the storage time, causing the color to darken. We can determine the freshness of this fish by measuring its color.     2. What are the measurement methods to measure the color of meat?   If check it by human eyes, it will take longer time and energy to get the result . And test result get by human eyes is subjective.   There is another method, color of meat can be determined by measuring the pigment content inside it, but this method will need a lot of time and chemical reagent.   Spectrophotometer will be the best measurement method. After measurement, the meat color value can be directly seen on the instrument.   3. How to measure the color of meat by spectrophotometer?     Measurement Condition   1. Mode: Reflectance 2. Light Source and Angle: D65/10 degree 3. Parameters need to Measure: color value CIE L*a*b or Hunter L*a*b. (CIE L*a*b is the most commonly used color index for measurement of meat. ) 4. Instrument: Spectrophotometer with glass sealed aperture     Test Method   1. Put the instrument directly on the chicken meat, press test then we can get the test result directly on the instrument screen.     After measurement, we can get the following test result. Sample Name L a b Chicken Meat 47.73 23.69 15.71   If any color measurement inquiry, you are welcome to contact us for more details. We will help to recommend the most suitable instrument for customers.

Haze meter made by CHNSpec Tech is designed to measure the both haze and total transmittance of transparent and semi-transparent material. It has been more than 6 months since our haze meter comes out. We have successfully done some projects. Today we will share it to let our customer know better about our instruments. Before we show the cases, we will introduce some definition about it.   1. What is haze? Haze is measured with a wide angle scattering test in which light is diffused in all directions which results in a loss of contrast. That percentage of light that when passing through that deviates from the incident beam by greater than 2.5 degrees on average is defined as haze.     2. Working Principle of Haze Meter When a beam of parallel light hits the sample and enters the integrating sphere, it is scattered on the sphere inner white coating, the total transmittance is measured when the optical trap outlet on the sphere is closed. When the optical trap is opened, haze will be measured.     3. Standards that CS-700 haze meter conforms to ASTM D1003/D1044, ISO13468, ISO14782, JIS K7105, JIS K7361, JIS K7136   4.
