Overview
Enviro Test Construct water detecting meter is encapsulated in a closed electrolyte cavity. The working electrode gold electrode is directly in contact with the solution to be tested.NO2- in solution is oxidized directly on the surface of the working electrode to form a current, which is proportional to the content of NO2- in solution.
Features

- There is no micro hole, and there is no danger of hole blockage in sewage
- Good versatility, three wire structure
- Easy maintenance, no need to replace the diaphragm
- Automatic temperature compensation
- No pressure balancing
- No interference by heavy metal ions
