Fluoride dosing, ammonia and nitrate monitoring and boiler water control need ion data continuously. This online analyzer measures 0.02–1000 mg/L depending on parameter at ±2% of reading, responds in 1–5 min and draws 10–50 mL/min of sample. Outputs include isolated 4-20 mA, Modbus RTU/TCP and optional Profibus with 2–4 alarm relays. Tell us your target ion.
