JIRS Anti-fouling Digital ORP Electrode RS485 4-20mA for Sewage Disinfection Aquaculture and Industrial Water Quality Control
This industrial online ORP sensor is built for continuous, reliable oxidation-reduction potential detection in harsh water environments. It adopts a dual‑output structure: RS485 (Modbus RTU) for digital communication and 4–20mA for universal analog compatibility, allowing direct connection to most industrial controllers without extra transmitters. The measuring range covers –2000 to +2000mV, with accuracy up to ±15mV and 1mV resolution, ensuring stable readings under real working conditions.
Equipped with automatic temperature compensation (0–60°C), IP68 waterproof rating, PPS/ABS corrosion-resistant housing, and PTFE liquid junction, the sensor performs well in corrosive, high‑humidity, and submerged environments. It supports easy one‑point calibration (86mV / 256mV standard solution) and is pre‑tested before shipment. The standard M12 connector and clear wiring ensure safe and fast installation.
Widely used in wastewater treatment, aquaculture, chemical engineering, electroplating, and environmental monitoring, this ORP sensor provides stable, accurate data to support process control and water quality management.
