The ProCon R7G Nexus ORP sensor transmitter features a platinum electrode for enhanced accuracy. Double junction with solid Nexus KCl infused reference makes it an excellent choice for general 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. 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.
