HS-815 BOD monitor

The BOD online monitor can be used to monitor the biological oxygen consumption of sewage organic matter. The measurement method is simple and no chemical needs to be added. The sludge extracted from the treatment plant or the sludge recovered from the sludge wave system can decompose the organic matter in the sewage and measure the oxygen demand of the process.

Main feature

1. On-site continuous monitoring of sensor technology.

2, fast response, no lag time.

3. Test accurate and effective suppression of interference technology.

4. The sensor is directly immersed in the water sample to be tested, without sample transportation and pretreatment.

5, fast response, real real-time continuous monitoring.

6, precision optical components, accurate testing in the UV visible band.

7, automatic air purging, can greatly extend the system's continuous running time, almost maintenance-free.

8, using photometric test, saving a lot of reagent consumption.
