1、 Product Overview

The colorimeter uses the principle of photoelectric colorimetry to test the chromaticity of aqueous solutions. This instrument is calibrated using the platinum cobalt color standard solution specified in the national standard GB5750, with degrees as the color measurement unit. It can be widely used for color measurement in power plants, purified water plants, water plants, domestic sewage treatment plants, beverage plants, environmental protection departments, industrial water, liquor industry, pharmaceutical industry, epidemic prevention departments, hospitals and other departments, in order to meet the prescribed water quality standards.
