Sensor performs direct measurement of ammonium ions without the need for costly sample preparation, delivering high accuracy under varying conditions thanks to automatic pH and temperature compensation. The standard configuration includes an ammonium ion electrode, a pH electrode, and a reference electrode (with optional potassium ions), and it covers a wide measurement range of 0–100 mg/L (WV) and 0–1000 mg/L (WX). It is designed for a wide range of water quality monitoring applications, including surface water, wastewater, tap water, reservoirs, drinking water, natural water, and domestic sewage.
