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.
