Pyxis ST-765SS-TCL Total Chlorine + pH Sensor – Sensor Only (Stainless Steel)
The Pyxis ST-765SS-TCL is a stainless steel, membrane-less multi-parameter sensor that measures total chlorine, pH, and temperature in a single probe using Pyxis Lab's bare-gold electrochemical detection technology. It ships sensor-only, without a flow reservoir kit, for installation into an existing housing. Dual isolated 4-20mA outputs plus RS-485 Modbus support direct integration with a PLC, SCADA, or third-party controller.
Description
The Pyxis ST-765SS-TCL is a stainless steel, membrane-less multi-parameter sensor that measures total chlorine, pH, and temperature from a single probe, using Pyxis Lab’s bare-gold electrochemical detection technology. It ships sensor-only, without a flow reservoir kit, for installation into an existing housing.
Total chlorine is measured over a 0-5ppm range. The reference electrode assembly is replaceable and front-loading, reducing startup polarisation time and giving a typical service life of up to 2 years, which reduces maintenance frequency.
Dual isolated 4-20mA outputs plus RS-485 Modbus, via an 8-pin connector, allow the sensor to integrate directly with a PLC, SCADA system, or third-party controller.
Why Use This
Total chlorine monitoring in one probe
Measures total chlorine, pH, and temperature simultaneously, reducing the number of separate sensors needed in a control loop.
Reduced maintenance
The replaceable, front-loading reference electrode typically lasts up to 2 years and cuts startup polarisation time.
Flexible controller integration
Dual isolated 4-20mA outputs and RS-485 Modbus connect directly to a PLC, SCADA, or third-party controller via an 8-pin connector.
Applications
- Total chlorine disinfection monitoring — tracks total chlorine and pH together in treated water
- Industrial process water treatment — bare-gold electrochemical sensing for continuous inline monitoring
- PLC/SCADA-integrated control loops — dual 4-20mA and RS-485 Modbus outputs feed directly into existing control systems
