Product Description

     KNF-107A ammonia nitrogen sensor, without reagents, is green and pollution-free, and can be monitored online in real time. Integrate ammonium ion, potassium ion (optional), pH and reference electrode, and automatically compensate potassium ion (optional), pH and temperature in the water body. It can be directly put into installation, which is more economical, environmentally friendly, convenient and quicker than traditional ammonia nitrogen analyzers. The sensor has a self-cleaning brush, which can prevent microorganisms from adhering, so that the maintenance period is longer, and it has excellent reliability. It adopts RS485 output and supports Modbus for easy integration.
