product key technologies

The Benchtop Colorimeter is a dedicated laboratory device engineered for precise determination of water solution colority. Built upon mature photoelectric colorimetric principle, it abandons the drawbacks of conventional manual visual comparison, delivering more objective, stable and repeatable measuring performance for routine water quality analysis.
To guarantee authoritative and consistent detection results, the instrument is strictly calibrated with standard platinum-cobalt color solution, adopting PCU as the unified measurement unit for water colority evaluation. This standardized calibration method aligns with mainstream industry norms, enabling accurate quantification of trace color variation in various water samples and laying a solid foundation for standardized water quality assessment.
This Benchtop Colorimeter features broad applicability across diverse industrial and public health sectors. It serves routine colority testing scenarios including power plant circulating water monitoring, purified water production lines, municipal waterworks, and domestic sewage treatment facilities. Meanwhile, it is also well-suited for quality control in beverage manufacturing, brewing processing, pharmaceutical production, as well as daily water inspection tasks of environmental protection departments, epidemic prevention agencies and hospitals.
Designed for practical laboratory use, the boasts streamlined structure and user-friendly operation workflow. It requires minimal professional training for operators to complete sample placement and data reading efficiently. With outstanding anti-interference capability and stable optical performance, it can adapt to complex water sample conditions and maintain long-term measuring accuracy. By precisely controlling water colority indicators, the instrument effectively assists all related institutions in keeping water quality within regulatory limits, becoming an indispensable analytical tool for water quality supervision, industrial production control and public health safety assurance.
