automatic processContinuous measurement.
Online colorimeter
3、 Operation and maintenance
Anti pollution measuresBefore entering the measurement pipeline and analysis tank, use the sample1MmofPPCotton filter.
Structural SeparationElectronic components are strictly isolated from wet chemical components, and transparent doors facilitate observation.
Simplify maintenanceRegularly replace the filter cotton and clean it according to the actual water quality/Calibration,.
Online colorimeter
4Through high-precision colorimetric methods, modular design, and automated processes, reliable online monitoring of water quality chromaticity is achieved, with flexible configuration (range)/Flow path/The output can be adapted to different application scenarios and is suitable for water quality monitoring fields that require high accuracy and automation.
