Pyxis ST-765SS-O3 Ozone + pH Sensor – Sensor Only (Stainless Steel)
Stainless steel ozone + pH sensor, 0-2ppm, sensor only with no flow reservoir. Dual 4-20mA + RS-485, 8-pin connector.
Pyxis ST-765SS-O3 Ozone + pH Sensor – Sensor Only (Stainless Steel)
The Pyxis ST-765SS-O3 is a stainless steel, membrane-less multi-parameter sensor that measures ozone, 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-O3 is a stainless steel, membrane-less multi-parameter sensor that measures ozone, pH, and temperature from a single probe. It is built on Pyxis Lab’s bare-gold electrochemical detection technology and ships sensor-only, without a flow reservoir kit, for installation into an existing housing.
The reference electrode assembly is replaceable and front-loading, reducing polarisation time on startup and delivering a typical service life of up to 2 years, which cuts down on maintenance visits. Ozone measurement covers a 0-2ppm range.
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, making it suited to plants that need ozone residual tracking alongside pH in one process tap.
Why Use This
Multi-parameter monitoring in one probe
Measures ozone, 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
- Ozone-based disinfection monitoring — tracks ozone residual and pH together in process water
- Industrial process water treatment — bare-gold electrochemical sensing suited to continuous inline monitoring
- PLC/SCADA-integrated control loops — dual 4-20mA and RS-485 Modbus outputs feed directly into existing control systems
FAQ
