ST-712 Inline pH & ORP Sensor

The Pyxis ST-700 series of 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.

Applications:

Industrial wastewater treatment, cooling water treatment

Features:

• Dual embedded transmitters in sensor housing: 4-20mA and RS-485 supporting MODBUS
• Longer maintenance cycles with high contamination resistance
• Eliminates the need of pre-amplifier and transfer signal directly in 4~20mA or digital protocol
• 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

Benefits:

• Large conjunction capacity (compared to replaceable electrode design) leading to longer service life
• Enhanced robustness when controller is away from sample point
