The Pyxis ST-700 series of pH, ORP, and conductivity probes are designed to simplify installation, calibration, and in-use operation in industrial wastewater and cooling water applications. These probes have an embedded 4~20mA transmitter. The oversized platinum disk ORP and the flat pH bubble sensing elements increase resistance to contamination. The double salt bridge design with large junction capacity ensures a long sensor life with minimum maintenance. The Pyxis ST-720/725 Probe only Measures Conductivity Dual embedded transmitters in sensor housing: 4-20mA and RS-485 supporting MODBUS. Large conjunction capacity (compared to replaceable electrode design) leading to longer service life. Longer maintenance cycles with high contamination resistance. Eliminates the need of pre-amplifier and transfer signal directly in 4~20mA or digital protocol. Enhanced robustness when controller is away from sample point.
