Cr Chromium Analyzer Water Quality Sensor Photoelectric Colorimeter
Principle and Application of Total Chromium Analyzer
Chromium is one of the essential micronutrients of living things.
The toxicity of chromium is related to its valence state. It is
generally believed that the toxicity of hexavalent chromium is 100
times higher than that of trivalent chromium. Therefore, hexavalent
chromium has been defined as one of the indicators of total
quantity control in China.
Principle: under the condition of high temperature, oxidant
oxidizes the chromium compound in the water sample to hexavalent
chromium. In acid medium, hexavalent chromium reacts with
chromogenic agent to form a purple-red complex. The absorbance of
the complex is proportional to the chromium content in the water
sample, the content of total chromium in water sample was obtained.
The main application scenarios are the monitoring of enterprise
rainwater and sewage, the monitoring of total copper content in
municipal pipe network, pumping station, groundwater, river water,
lake water and sea water.
Feature
- Digestion using integrated valve design, sealing effect is good, no
leakage.
- Digestion valve high temperature 200°, high pressure 2Mpa.
- Touch screen with industrial design, strong adaptability to
environment.
- Pipe material USES acid alkali resistance of PTFE material.
