an overview of the

the colorimeter uses the photoelectric colorimetry principle to test the chromaticity of the aqueous solution. this instrument adopts the national standard gb5750

platinum & ndash; standard solution of cobalt chromaticity was calibrated to c & throughout; as a unit of color measurement. can be widely used in power plants, pure water

factories, waterworks, sewage treatment plants, beverage plants, environmental protection departments, industrial water, wine industry, pharmaceutical industry, prevention

to determine the chroma of the epidemic department, hospital and other departments so as to meet the prescribed water quality standards.

the working conditions

1, working environment temperature using 5 ~ 35 ℃ storage - 20 ~ 55 ℃

2. the humidity in the working environment is no more than 80%rh

3. power supply voltage: 220v, 50hz

4. the instrument should be placed horizontally on a stable laboratory table, effectively avoiding the direct light source. and no strong magnetic interference and strong vibration source.

5. there should be no obvious dust or corrosive gas in the surrounding air.
