Online ORP Controller for Disinfection Control

消毒控制用在线 ORP 控制器

Pools, cooling towers, produce wash lines and drinking water plants dose disinfectant against an ORP setpoint. This controller reads −1000 to +1000 mV with ±2 mV accuracy and drives 2–4 relays by on/off, proportional or PID control, plus a 4–20 mA output. Sensors tolerate 60–80 °C and 6–10 bar. Tell us your dosing equipment.
