After the water sample is mixed with the conditioner, the cadmium in the sample reacts with the indicator in the presence of an alkaline environment and the indicator (TPPS4) to form a colored complex, and the analyzer detects the color change, and the This change is converted into cadmium value and output. The amount of colored complex produced is equivalent to the amount of cadmium.

The total cadmium online automatic analyzer is an optical heavy metal online analyzer designed in accordance with national environmental protection standards. It is used for simultaneous online analysis of multiple heavy metal elements in surface water, industrial process water and industrial wastewater.

1. Sampling inspection of large watershed environment.


2. Practical use by laboratory researchers.


3. Monitoring of fishery breeding and breeding environment.


4. Monitoring of sewage outlets of sewage plants.


5. Rivers, lakes, streams, etc.
