Self-cleaning online ammonia sensor requires no reagents, green and pollution-free, real-time online monitoring. Standard ammonium ion electrode, pH electrode and reference electrode (potassium ion optional), in the process of measuring ammonia and nitrogen in the water body, automatic pH and temperature compensation, so that the measurement value is more accurate. The sensor can be installed directly, compared with the traditional ammonia analyser, more economical and environmentally friendly, convenient and quick. The sensor is equipped with a self-cleaning brush, which prevents microbial adhesion and allows for longer maintenance intervals and excellent reliability.
