Online ammonia nitrogen analyzer, NHNK-1000
0.00৳
ibration, 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. The benefits of NHNK-1000 online ammonia nitrogen analyzer include :
1) Low initial investment
2) Operational costs reduced by up to 50%
3)Improved discharge values
4) Online help integrated in the ammonia nitrogen sensor

Main Features
The Ammonia Nitrogen Sensor is directly output RS485 signal
High precision, high stability and strong anti-interference ability
The ion sensor enables long term stable measurement
BOQU digital ammonia nitrogen(NH4-N) sensor using ion electrode method which is designed for aeration control in wastewater treatment
The NH4 ion selective electrode is a grid film electrode，the material of which mainly uses a special organic ion exchange membrane that dissolves in the organic solution and penetrates with the PVC mesh.the ammonia nitrogen sensor is widely used include: drinking water, fertilizer, and refrigerant.
Real-time data transmission allows you to get timely and accurate data on monitoring water
