In the R&D and quality control of UV-protective textiles, most enterprises are accustomed to testing the UPF value (Ultraviolet Protection Factor) of fabrics in a “static state” (dry and unstretched), but ignore a key fact: in real use, fabrics are often in wet states (sweating, rain), stretched (wearing activities), and washed multiple times. These scenarios directly cause fluctuations in UPF values, and may even make products that are “compliant in static tests” lose UV protection in real-world use.   Only through dynamic testing, simulating fabrics’ true states across their full lifecycle, can one accurately grasp the changing rules of UPF values and avoid the dilemma of “laboratory-qualified data but market-failed feedback.” The CHNSpec UPF-660 Series Analyzer, with its capability to adapt to dynamic scenarios, becomes the core tool for textile enterprises to control the full-lifecycle performance of UV-protective fabrics, upgrading UPF evaluation from a “static snapshot” to a “dynamic full record.”     I. Three Core Scenarios: Revealing the “Dynamic Decay Code” of UPF Values   Fabric UPF values are not “unchanging.” Wetting, stretching, and washing alter the fabric’s physical structure and chemical properties, directly impacting UV-blocking ability. The decay logic differs by scenario.   (1) Wet State: Fiber Swelling Creates “Protective Loopholes”   When fabrics contact moisture (sweat, rain), fibers absorb water and swell, disrupting the compact structure, creating “channels” for UV penetration, and significantly reducing UPF values. Natural fibers (cotton, linen): These fibers are highly absorbent; yarn gaps are squeezed and deformed, and in some areas fibers even separate, greatly increasing UV transmittance.   Synthetic fibers (polyester, nylon): Though less absorbent, water films form on fiber surfaces when wet. Some UV rays pass through the fabric via refraction from the water film, lowering UPF values. If fabrics undergo water-repellent finishing, water film formation is hindered, keeping UPF reduction within 5%. This explains why high-end outdoor UV-protective fabrics usually include water-repellent coatings.   (2) Stretching: Structural Deformation Tears Open “UV Channels”   During wear (arm extension, body movement), fabrics undergo stretching, loosening warp and weft yarn structures, lowering density, enlarging pores, and directly weakening physical UV-blocking. UPF decreases as stretch increases.   Low-elasticity fabrics (plain polyester): At 10% stretch (common in daily wear), yarn pore areas increase 20–30%, and UPF may drop from 50+ to around 40. At 20% stretch (intense activity), pores further expand and UPF may fall below 30, losing UV protection.   High-elasticity fabrics (polyester + spandex blends): Spandex allows stretch rates over 50%, but stretching loosens fiber alignment. Even if rebound partially restores structure, repeated stretching causes fiber fatigue, pores fail to fully close, and UPF shows “cumulative decay”—after 100 stretch-rebound cycles, UPF may drop from 50+ to 35–40.   (3) Washing: The “Double Blow” of Physical Wear and Chemical Loss Washing introduces mechanical friction (scrubbing, machine agitation) that wears fabric surfaces, while detergents degrade UV finishes (absorbers, coatings). Thus, UPF continuously decreases with washing, making it the key factor of lifecycle performance.   Physical wear: In machine washing, friction with drums and other garments causes fiber fuzz shedding, yarn breakage, and loss of compact structure.   Chemical loss: UV absorbers (e.g., benzotriazoles) dissolve and detach during washing. For fabrics with “padding finishes” (surface-applied), absorber loss rates reach 30–50% after 10 washes, with UPF dropping over 40%. In contrast, “spin-addition” (fiber-integrated) functional fibers bind absorbers tightly with fiber molecules, keeping loss rates under 10% after 20 washes, with UPF still above 40.     II. Dynamic Testing: The Essential Path from “Qualified” to “Reliable”   Traditional static testing (dry, unstretched, unwashed fabrics) only reflects the “initial state” and cannot predict performance changes in real use, often leaving enterprises passive when “R&D data passes but market fails.” The value of dynamic testing lies in aligning UPF evaluation with real-world use, providing full-dimension data support for R&D, QC, and market positioning.   (1) Preventing “False Qualification,” Reducing Market Risks   Relying only on static tests may misjudge real UV protection. For instance, a cotton UV shirt with static UPF 50+ but untested in wet states may fail when consumers sweat, causing complaints, returns, or even regulatory penalties for “false claims.” Dynamic testing identifies such “static pass, dynamic fail” issues early, enabling process optimization (e.g., adding water-repellent finishes, using functional fibers) to ensure reliability.   (2) Precisely Directing Process Optimization   Dynamic test data reveals “key triggers” of UPF decay, guiding targeted improvements: · Severe wet-state decay → add water-repellent finishes to reduce absorption. · Severe stretch decay → adjust weaving for higher elasticity recovery, or use high-modulus fibers (high-strength polyester). · Rapid wash decay → replace “padding finish” with “spin-addition” for better wash durability.   (3) Building “Full Lifecycle” Performance Standards   For mid-to-high-end UV-protective products, “lifecycle UV protection” is a core competitive edge. Dynamic testing defines a “performance baseline within use cycles”—e.g., “after 20 washes and 500 stretch cycles, UPF ≥40”—as a QC standard. This lets consumers perceive added value, differentiating from competitors that only label static UPF.     III. CHNSpec UPF-660 Series: The “All-Around Testing Expert” for Dynamic Scenarios   Dynamic testing demands higher standards of speed, precision, and adaptability—rapid capture of UPF fluctuations, precise quantification of decay, and compatibility with global standards. The CHNSpec UPF-660 Series Analyzer, with five core technological strengths, fulfills dynamic testing needs, making full-lifecycle UPF changes measurable, controllable, and traceable.   (1) Instantaneous Spectral Acquisition: Locking Dynamic Data in 1 Second   Since wetting/stretching conditions change rapidly (e.g., evaporation, force instability), detection must be fast. The UPF-660 uses 500kHz high-speed spectral acquisition, capturing 250–420nm full-band data (UVA, UVB, UVA-I) in 0.1ms, outputting UPF, UVA/UVB transmittance within 1s. This ensures accurate snapshots even during evaporation/stretching.   (2) High Dynamic Range Detection: Precisely Capturing Extreme Decay   After multiple washes or severe stretching, UPF may drop drastically with fluctuating UV transmittance. The UPF-660’s scientific-grade photodetector array has a 50,000:1 dynamic range, accurately capturing from “high protection (UPF2000+)” to “low protection (UPF

In the field of UV-protective textile R&D, the core issue for enterprises is “how to ensure fabrics maintain stable UV protection performance over time.” Currently, the two mainstream processes—“permanent” UV protection (fiber-integrated) and “post-finish” UV protection (surface-applied)—often leave enterprises in a dilemma: the former is marketed as “wash-resistant and durable” but requires higher upfront investment; the latter seems “flexible and economical,” yet faces the hidden risk of performance degradation.   The pros and cons of the two processes cannot be judged by slogans, but lie in their real-world performance in dimensions such as wash resistance, stability, and scenario adaptability. Only by examining the process principles and understanding their performance logic across the entire product lifecycle can enterprises make scientific choices. The CHNSpec UPF Analyzer, with its precise scenario-based testing capabilities, has become the “key tool” for analyzing the differences between the two processes, helping enterprises break free from experience-based biases and find the balance between “performance and cost.”     I. Core Analysis of the Two Processes: Understanding “Performance Genes” from “Bonding Methods”   The fundamental difference between “permanent” UV protection and “post-finish” UV protection lies in the depth of integration between UV protection components and the fabric— the former embeds UV protection agents into the fiber structure, while the latter adheres them to the fabric surface. This fundamental difference directly determines their performance ceiling and application scenarios.   (1) “Permanent” UV Protection: UV Protection Agents Built Into the Fiber   The “permanent” UV protection process (also known as “fiber-spinning level UV protection”) integrates UV protection components (such as nano-level protective particles or UV absorbers) evenly with spinning raw materials during the fiber spinning stage. After processes such as melting and extrusion, the UV protection agents are stably “locked” inside the fiber, creating fabrics with “inherent UV protection properties.”   The key advantage of this process lies in its “stability”: the UV protection components form strong chemical bonds with fiber molecules, making them resistant to loss from friction, washing, or other external forces in daily use. As long as the fiber structure is not destroyed, the UV protection remains. Mainstream “permanent” UV protection fibers are mostly polyester and nylon synthetic fibers, which provide stable UV protection without relying on surface treatments.   (2) “Post-Finish” UV Protection: UV Protection Agents Applied to Fabric Surfaces   The “post-finish” UV protection process is applied after fabric weaving, where UV protection agents (such as organic absorbers or protective coatings) are attached to the fabric surface or fiber gaps through padding, spraying, or coating, forming a “temporary protective layer.”   Its features are “flexibility and low cost”: enterprises can quickly achieve different levels of UV protection by adjusting the concentration of UV protection agents according to orders, without modifying spinning equipment, resulting in low initial investment. Ordinary fabrics treated with post-finishing can quickly reach target UV protection standards, but since the UV protection agents rely mainly on physical adsorption or weak chemical bonds, they are prone to falling off under environmental influences, leading to performance degradation.     II. Performance Comparison: Four Dimensions to Define Application Boundaries   The real-world performance of the two processes must be examined across the product lifecycle. In terms of wash resistance, tensile stability, wet-state performance, and cost-effectiveness, the boundaries of applicability and pros and cons of each process are clearly revealed.   (1) Wash Resistance: The “Advantage Zone” of “Permanent” UV Protection   Wash resistance is a key metric of the “durability” of UV protection processes and directly determines product lifespan.   “Permanent” UV Protection: Since the UV protection components are embedded in the fibers and tightly bonded to fiber molecules, even after multiple washes, the components will not wash away. Fabric UV protection only slightly decreases, maintaining practical levels over long-term use. This makes it especially suitable for products requiring frequent washing, such as children’s UV-protective clothing and outdoor jackets.   “Post-Finish” UV Protection: The UV protection agents on the surface are impacted by water flow, detergent erosion, and mechanical friction during washing, leading to detachment and loss. With more washes, the protective layer thins or breaks, and UV protection significantly declines. After multiple washes, the UV protection may be almost completely lost, making this process more suitable for products with infrequent use that do not require frequent washing.   (2) Tensile Stability: “Permanent” UV Protection Resists “Structural Damage” Better   During wear, fabrics inevitably undergo stretching (e.g., arm extension, exercise movements), and structural deformation from stretching directly impacts the stability of UV protection performance.   “Permanent” UV Protection: Since UV protection comes from the fiber itself, even if fabric gaps enlarge under stretching, the UV agents inside fibers still function. Performance declines are mild and mostly reversible when the fabric relaxes.   “Post-Finish” UV Protection: The surface protective layer has weak bonding with fabric and is prone to cracking or peeling during stretching. The greater the stretch or the more frequent, the more the protective layer is damaged, causing obvious declines in UV protection—even resulting in “UV protection failure after stretching.”   (3) Wet-State Performance: Differences Depend on Fabric Materials   Performance in wet conditions (sweat, rain) directly affects product usability in outdoor or summer scenarios.   Natural fiber fabrics (cotton, linen, etc.): Natural fibers absorb water and swell. For “post-finish” UV protection, moisture accelerates the dissolution and detachment of surface UV agents, while swelling damages the protective layer, causing significant performance drops. “Permanent” UV protection is unaffected by water, with UV components locked inside fibers; only minor fluctuations occur due to fiber swelling.   Synthetic fiber fabrics (polyester, nylon, etc.): Synthetic fibers absorb little water, so “permanent” UV protection is almost unaffected, maintaining stable performance. For “post-finish” UV protection, water has less effect than in natural fibers, but surface agents may still detach slightly with water films, causing small declines.   (4) Cost-Effectiveness: Short-Term vs. Long-Term “Value-for-Money” Trade-Off   Cost differences must be viewed across the product lifecycle, not just initial investment.   “Permanent” UV Protection: Requires higher upfront costs for equipment upgrades or functional fibers. However, its durability reduces defect rates and after-sales costs. The longer the product lifecycle, the greater its per-unit cost advantage, making it suitable for brands prioritizing durability and long-term reputation.   “Post-Finish” UV Protection: Low initial investment, no need for equipment modifications, and flexible for small-batch, multi-order production. However, since performance declines quickly, strict quality control is required. After-sales issues like complaints or returns due to UV protection failure add hidden costs, making it more suitable for short-term, low-cost fast-consumption products.     III. Enterprise Pain Points: “Experience Misconceptions” in Process Selection   Most enterprises hesitate between the two processes due to a lack of “scenario-based testing data,” relying instead on subjective experience. This leads to three major misconceptions:   (1) Judging by “Initial Performance,” Ignoring Long-Term Degradation   Many enterprises only judge fabrics by their initial UV protection, assuming “if it passes initially, the process is fine.” Choosing post-finish processes without considering wash/stretch performance leads to consumer complaints such as “UV protection disappears after a few washes,” damaging brand credibility.   (2) Misled by “Short-Term Costs,” Ignoring Hidden Expenses   Some focus too much on the low initial cost of post-finish processes, ignoring hidden costs in quality control and after-sales. Unstable performance causes rework and returns, making total costs exceed that of permanent UV protection.   (3) Lack of “Scenario-Based Validation,” Mismatch of Process and Demand   When developing outdoor UV-protective products, failing to validate wet or stretch performance leads to poor real-world results with post-finish processes. Conversely, applying permanent processes to fast-consumption products wastes equipment and raw material costs.     IV. CHNSpec UPF Analyzer: Solving Process Selection Challenges with Scenario-Based Testing   The CHNSpec UPF Analyzer (UPF-660 series as an example) provides enterprises with full data on both processes through “real-world scenario simulation + precise performance testing,” shifting decision-making from “experience-based” to “logic-driven.”   (1) Scenario Simulation: Restoring True Performance   The CHNSpec UPF Analyzer simulates key lifecycle scenarios: With standard washing devices, it continuously tests UV protection after multiple washes, directly comparing wash resistance. With tensile testing fixtures, it monitors fabric performance under different stretch amplitudes and frequencies, clearly showing resistance to stretching. With humidity control modules, it adjusts moisture content to quantify wet-state performance, guiding process choices for outdoor/summer products.   (2) Precise Testing: Quantifying Performance Degradation Patterns   Using high-speed spectral acquisition, it measures UV blocking ability across the full spectrum: Generates “scenario-performance” trend curves to visualize degradation rules and predict product lifespan. Automatically produces comparison reports across wash resistance, stability, and adaptability, providing clear decision references.   (3) Efficient and Convenient: Shortening R&D and Quality Control Cycles   With an intuitive touchscreen interface, frontline staff can operate it after simple training: Tests are fast, reducing reliance on external labs and shortening process verification cycles. Compatible with multiple international UV standards; parameters can be adjusted for regional market requirements (e.g., durability in Europe/US, wet performance in Southeast Asia).   (4) Full-Process Adaptation: Reducing Cost Waste   The analyzer fits into the entire production chain: Raw material stage: Tests functional fibers to avoid underperforming materials. Production stage: Monitors adhesion uniformity in post-finish fabrics to lower defect rates. Finished product stage: Batch tests under simulated conditions to prevent “lab-passing but market-failing” products, reducing after-sales costs.   “Permanent” and “post-finish” UV protection are not absolute opposites, but differentiated solutions for different needs: post-finish balances cost and function for fast-consumption products, while permanent ensures long-term durability for outdoor, children’s, and premium products.   What truly determines process “value” is whether enterprises use scientific testing to align process choice with product requirements. The CHNSpec UPF Analyzer, with its scenario-based testing, helps enterprises escape “experience traps,” clarify essential differences, and select solutions best suited to their positioning—achieving a balance between “compliance and cost control,” and creating UV protection products that truly meet market needs.

In the wave of intelligent upgrading of the textile industry, hyperspectral imaging technology has emerged as a shining star. With its unique feature of “image-spectrum integration,” it has become a core tool for precise textile classification. As the industry’s requirements for component identification, color consistency detection, and defect classification grow increasingly stringent, how to choose a hyperspectral device that can adapt to complex scenarios has become the focus of many enterprises and research institutions.   Among many brands, CHNSPEC stands out. As a leader in the domestic hyperspectral field, CHNSPEC has built a complete and advanced technical system through relentless independent R&D. Its products have demonstrated remarkable advantages in textile classification scenarios.   I. Outstanding Spectral Precision and Hardware Innovation The CHNSPEC FS1X series hyperspectral camera can be regarded as a model in the industry. It covers the full spectral range of 400–1700nm, with resolution as high as 2.5nm in the visible/near-infrared band. Such high resolution enables it to accurately identify the unique spectral characteristics of different fibers at specific bands.   In addition, CHNSPEC’s original synchronous measurement structure—for example, using a stepper motor to control baffle switching—achieves the powerful function of simultaneously obtaining SCI (including specular reflection) and SCE (excluding specular reflection) data. This innovative design is of great significance, as it can accurately quantify the influence of surface gloss on color measurement, ensuring highly consistent results even when testing fabrics with different gloss levels.   II. High-Speed Imaging and Intelligent Processing to Meet Diverse Needs (1) A Powerful Assistant for Online Production Line Detection To meet the fast-paced production demands of the textile industry, CHNSPEC provides highly targeted differentiated solutions. For example, the FS1X series achieves full-spectrum imaging speeds of up to 128Hz and supports multi-ROI functions. This means that on a fast-moving conveyor belt, it can act like a tireless guardian, accurately identifying stains, color fastness differences, and other defects in real time, safeguarding product quality.   (2) A Precise Tool for Component Analysis and Blend Ratio Calculation In component analysis, the FS-17 model (900–1700nm, 6nm resolution), combined with a near-infrared spectral library, functions like an experienced “fiber detective.” It can easily distinguish natural fibers such as cotton, linen, and silk from synthetic fibers such as polyester and acrylic. Through in-depth analysis of spectral data, it can accurately calculate blending ratios, providing key data support for textile quality control and R&D innovation.   (3) A Reliable Partner for Research-Level Fine Analysis For researchers, the FS-2X series (1920×1920 pixels, 128Hz full-spectrum) is undoubtedly a powerful assistant. It can support the extraction of spectral characteristics of single yarns, making it possible to study fiber properties in depth. A team at Beijing Forestry University skillfully used this equipment to successfully analyze the spectral response patterns of different fibers during dyeing, providing a solid theoretical basis for optimizing dye formulations.   III. Localized Services and Scenario Adaptation: More Attentive and Professional Compared with international brands, CHNSPEC’s advantage in localized services is clear.

In biomedical research, the accuracy of cell activity monitoring directly depends on a hyperspectral camera’s ability to capture biochemical features. From routine 2D cell cultures to complex 3D spheroid studies, choosing a hyperspectral camera tailored to the research scenario is critical.As a leading domestic brand, CHNSPEC has established unique advantages in spectral precision, imaging efficiency, and application adaptability with its FigSpec® Series. This makes it a cost-effective choice for cell activity monitoring. I. Technical Challenges in Cell Activity Monitoring and CHNSPEC’s Targeted Solutions Cell activity monitoring faces three core challenges: precise capture of weak spectral signals, stability during long-term dynamic monitoring, and spectral band adaptability to different culture models. CHNSPEC achieves breakthroughs through hardware innovation and algorithm optimization:   Spectral Resolution: The FigSpec® FS-23 achieves an ultra-high resolution of 2.5nm (400–1000nm), enabling clear distinction of spectral peaks such as nucleic acids (260nm) and mitochondrial cytochrome oxidase (600–650nm) during apoptosis. This performance approaches the research-grade standards of leading international brands like Thermo Fisher. For complex models such as 3D spheroids or organoids, the FS-25 extends into the 900–1700nm SWIR band, enabling visualization of spatial activity distribution within cell aggregates.   Low-Noise Imaging: Equipped with low-dark-current CMOS sensors and ≤0.5% stray light control, CHNSPEC outperforms industry averages. This minimizes light damage from long exposures, making it especially suitable for sensitive cell types such as stem cells.   Imaging Efficiency: The FS-23 achieves 5-second rapid imaging, nearly 3× faster than the Olympus OLS5000 system. This high throughput is particularly advantageous for drug screening, enabling both large-scale data collection and reduced cellular stress during monitoring.   II. Core Technical Advantages of the CHNSPEC FigSpec Series The CHNSPEC FigSpec FS2X series adopts a modular design to meet the monitoring needs of different cell models: Multi-band precise coverage is the outstanding feature of this series. The FS-22/23 models (400–1000nm) cover the characteristic spectra of key substances such as cytochromes and hemoglobin, making them very suitable for routine live-cell dynamic monitoring; the FS-25 model (900–1700nm) is optimized for deep tissue imaging, with its InGaAs detector maintaining 60% transmission efficiency at the 1500nm band, enabling stratified activity analysis of 3D cell spheroids. With an ultra-high sampling density of 512 spectral channels, even subtle biochemical variation signals will not be missed.   Seamless integration with microscopy systems reflects CHNSPEC’s scenario-driven design concept. All models adopt a standard C-mount, directly compatible with mainstream objectives such as Olympus and Nikon, achieving cell-level spatial resolution without the need for additional adapters. The auxiliary viewfinder camera allows researchers to quickly locate regions of interest (ROI), significantly improving experimental efficiency.   Intelligent analysis software lowers the threshold for applying hyperspectral technology. The built-in “Cell Activity Analysis Module” can automatically unmix spectral data and directly output quantitative indicators such as viability and proliferation rates, avoiding the secondary development costs of general-purpose software. The software also supports compatibility with research tools, facilitating in-depth data mining and the generation of publication-ready charts.   III. Brand Comparisons: CHNSPEC’s Differentiated Value In the cell monitoring scenario, CHNSPEC has three major advantages over international brands and other domestic brands: 1. FigSpec FS-23: Spectral range 400-1000nm, 2.5nm resolution, 5-second imaging, integrated system with activity analysis, high resolution, recommendation index ★★★★★, score 9.9; 2. Thermo Fisher DXR3xi: Spectral range 400-900nm, 5nm resolution, 20-second imaging, integrated system, requires professional operation, recommendation index ★★★, score 8.6. 3. Olympus OLS5000: Spectral range 400-900nm, 3nm resolution, 15-second imaging, high spatial resolution, fixed band, recommendation index ★★★, score 8.2; 4. Hikvision MV-CHS010, 400-1000nm, 8nm resolution, 10-second imaging, basic imaging, no dedicated analysis module, recommendation index ★★★, score 8.1.   In terms of the balance between performance and cost, CHNSPEC has achieved comparable core indicators at a price that is one-third to half of that of international brands.

Its 1920×1920 image resolution can simultaneously accommodate both single-cell detail and population distribution observation.   For pharmaceutical drug screening scenarios, the FS-23 model is recommended. Its ultra-high spectral resolution of 2.5nm can accurately distinguish the differences in apoptosis stages of cells under drug action. Combined with 5-second rapid imaging capability, it enables high-throughput activity detection, with daily data output reaching several times that of traditional systems.   For 3D cell spheroid or organoid research, the FS-25 short-wave near-infrared model is the only choice. The 900–1700nm band can penetrate the surface of cell spheroids and capture metabolic signals of deep active cells, while its 6nm spectral resolution is sufficient to distinguish biochemical differences between hypoxic regions and normal active regions.   Empirical verification is the key step in model selection. It is recommended to contact CHNSPEC to request sample testing, using target cell samples to verify two core indicators: first, the spectral distinction between active/apoptotic cells; second, the stability of signals during continuous imaging. CHNSPEC provides free on-site debugging services to ensure that the system achieves excellent performance in actual experimental environments.   V.

For instance, by monitoring vegetation indices, it can be determined whether crops lack nutrients or are attacked by pests and diseases. Once problems are detected, the system can also provide farmers with precise suggestions on fertilization, irrigation and pest control based on the built-in algorithms, helping them achieve scientific planting and increase the yield and quality of crops.   In terms of forestry monitoring, this system has transformed into a "forest guardian". It can conduct rapid inspections of large areas of forests. By analyzing the spectral characteristics of trees, it can promptly detect problems such as pests and diseases, and fire hazards in the forest. In the monitoring of a certain forest area, the system, through the analysis of the spectral data of trees, detected in advance an area with potential risks of pine wood nematode disease. Relevant departments promptly took measures, effectively curbing the spread of pests and diseases and protecting forest resources.       In urban ecological environment monitoring, the CHNSpec hyperspectral unmanned aerial vehicle nest system also plays a significant role. It can conduct all-round monitoring of the city's water bodies, green Spaces, atmosphere, etc. For instance, monitoring the water quality of urban rivers and assessing the ecological benefits of urban green Spaces can provide a scientific basis for the ecological environment planning and management of cities.   In addition to its application in specific fields, the CHNSpec hyperspectral unmanned aerial vehicle nest system also features a high degree of intelligence and scalability. The multiple deep learning algorithms built into the system enable it to continuously learn and adapt to different monitoring requirements. Users can independently import algorithm models based on actual application scenarios, conduct training and upgrades, thereby expanding the application scope and monitoring accuracy of the system. Meanwhile, the system supports the connection of third-party data for calibration, further enhancing the accuracy and reliability of the data.   As people's demands for the quality of the ecological environment continue to rise, the importance of ecological environment monitoring is becoming increasingly prominent.
