Pyxis ST-765SS-NCL Monochloramine + pH Sensor – Sensor Only (Stainless Steel)
Stainless steel monochloramine + pH sensor, 0-5ppm, sensor only with no flow reservoir. Dual 4-20mA + RS-485, 8-pin connector.
Pyxis ST-765SS-NCL Monochloramine + pH Sensor – Sensor Only (Stainless Steel)
The Pyxis ST-765SS-NCL is a stainless steel, membrane-less multi-parameter sensor that measures monochloramine, pH, and temperature in a single probe using Pyxis Lab's bare-gold electrochemical detection technology. It is suited to chloramine-based disinfection monitoring in potable and process water, and ships sensor-only without a flow reservoir kit. 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-NCL is a stainless steel, membrane-less multi-parameter sensor that measures monochloramine, 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.
Monochloramine is measured over a 0-5ppm range, making the sensor well suited to chloramine-based disinfection monitoring in potable and process water. The reference electrode assembly is replaceable and front-loading, reducing startup polarisation time and giving a typical service life of up to 2 years.
Dual isolated 4-20mA outputs plus RS-485 Modbus, via an 8-pin connector, support direct integration with a PLC, SCADA, or third-party controller.
Why Use This
Chloramine disinfection monitoring
Tracks monochloramine alongside pH in one probe, supporting disinfection control in potable and process water systems.
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
- Potable water disinfection monitoring — tracks monochloramine and pH in drinking water systems
- Chloramine-based process water disinfection — continuous monitoring for treatment programmes
- PLC/SCADA-integrated control loops — dual 4-20mA and RS-485 Modbus outputs for direct system tie-in
