Pyxis Inline pH & ORP Probe - ST-712

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-712 Probe Measures pH & ORP

• 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.
• Specially designed pH/ORP electrodes tolerant to short time frozen during shipment or storage.
• Stainless steel solution grounding point on sensor to stay away from ground loop problems.
