NHNK-1000 Online Ammonia Nitrogen Analyzer BOQU Instrument has new online ammonia nitrogen analyzer,model is NHNK-1000,it's popular used for wastewater treatment plants. Controlling discharge values for ammonia nitrogen by a simple continuous ammonia nitrogen sensor measurement,it's impossible in the past.BOQU Instrument provides this basis for a specific ammonia nitrogen parameter process control.During calibration, the NHNK-1000 Online ammonia nitrogen analyzer can be adjusted to a reference value which was photometrically determined in the lab for the specific medium to be analysed. In this way, the matrix effects of the wastewater are recorded and automatically taken into account for all readings. The biggest result is that calibration against standards is no longer required.
