The ProCon R7C Nexus ORP sensor transmitter features a gold electrode for enhanced accuracy. Double junction with solid Nexus KCl infused reference makes it excellent for complex process media applications. All measurement functions are combined in one compact body: measuring electrode, temperature sensor, and inner reference chamber.

Output options: 2‑wire 4-20mA, 4‑wire, or 4-20mA + RS485, simplifying calibration and communication with remote displays and controllers. No preamp required. Measurement range -1000 to 1000 mV, accuracy ±1mV, temperature compensated. Operating temperature -10 to 80°C, max pressure 145 psi (10 bar). 3/4″ NPT connection. Applications: process control, water quality, sanitization, neutralization, effluent monitoring, cooling towers.
