JIRS GO-300 and GO-400G are industrial online ORP (Oxidation-Reduction Potential) sensors built for continuous water quality monitoring. Combining platinum measuring electrodes, gel-filled reference systems, and anti-fouling PTFE diaphragms, these redox sensors deliver fast 5-second response and long-term stability with zero electrolyte refilling. The GO-300 (ABS body, 0–60 °C) covers general wastewater treatment, while the GO-400G (high-temperature glass body, 5–100 °C) handles boiler water and chromium-containing wastewater.

This industrial ORP sensor is designed for online oxidation-reduction potential monitoring in water systems. It provides dual output: RS485 Modbus RTU and 4–20mA analog, supporting stable long-distance transmission and easy integration with PLC, DCS, and SCADA systems. With high accuracy, IP68 waterproof, corrosion-resistant housing, and automatic temperature compensation, it works reliably in wastewater, aquaculture, chemical processing, and environmental monitoring. Simple to activate, calibrate, and maintain, it delivers stable data for long-term online use.
