Practical colorimeter-Fornitore globale

4th Floor, Building C, Weijian Technology Industrial Park, Beihuan Road, Shiyan Street, Bao'an District, Shenzhen

Detection Principle

The YC-781 practical colorimeter produces a standard colorimetric solution sequence based on GB11903-89 "Platinum Cobalt Colorimetric Method for Water Quality" and stores it in a microcomputer system using spectrophotometry. By importing cold light sources and narrowband interference technology, the absorbance of water samples is measured by spectrophotometry. After calculation by the instrument chip, the chromaticity value (mg/L) in the water quality is directly displayed.
