The Online Ammonia Nitrogen Analyzer reliably and accurately measures ammonia concentration in a variety of applications, including raw water monitoring and nutrient removal from wastewater. No reagents are required, they are green and non-polluting, and they can be monitored online in real-time. The NH4 Probe uses three electrodes: an ammonium ion-selective electrode, potassium (optional) electrode, a pH electrode, and two reference electrodes, which automatically compensate for potassium (optional), pH, and temperature in water.
The device can be directly put into an installation that is more economical, environmentally friendly, and convenient than a traditional ammonia nitrogen analyzer. It adopts RS485 output and supports Modbus for easy integration.
FEATURES :
- Digital sensor, RS-485 output, support MODBUS;
- No reagents, no pollution, more economical and environmentally friendly;
- The principle of ion-selective electrode;
- Automatically compensates for pH and temperature in water;
- Electrodes can be replaced individually.
