Ion Electrode Method Digital NH4-N Meter For Groundwater Monitoring

ISE Principle RS485 Interface NH4-N Controller For Surface Water Monitoring

The ion selective sensor is directly installed in the active sludge tank of the sewage treatment plant for measurement without any sample pretreatment or sample transmission. The whole measurement system includes sensor and transmitter; the sensor contains electrodes, and the transmitter has a display and operation unit. The sensor is used to monitor the concentration of ammonia nitrogen; the sludge tank, the outlet of the primary sedimentation tank.
