Pyxis ST-765SS-FCL Free Chlorine + pH Sensor – Sensor Only (Stainless Steel)
Stainless steel free chlorine + pH sensor, 0-5ppm, sensor only with no flow reservoir. Dual 4-20mA + RS-485, 8-pin connector.
Pyxis ST-765SS-FCL Free Chlorine + pH Sensor – Sensor Only (Stainless Steel)
The ST-765SS-FCL sensor-only variant is a stainless steel-bodied, membrane-less sensor that measures Free Chlorine (0-5ppm) alongside pH and temperature using Pyxis Lab's bare-gold electrochemical detection technology. It ships without a flow reservoir kit, for installations with an existing flow cell or in-line tee. The replaceable front-loading reference electrode gives a typical service life of up to 2 years.
Description
The ST-765SS-FCL sensor-only variant is a stainless steel-bodied, membrane-less sensor that measures Free Chlorine (0-5ppm) alongside pH and temperature, using Pyxis Lab’s bare-gold electrochemical detection technology with internal compensation to keep readings consistent with DPD wet chemistry. The stainless steel body suits industrial and wastewater applications where a CPVC body would not be appropriate.
This configuration ships without a flow reservoir kit, intended for installations that already have an existing flow cell or in-line tee in place, avoiding the cost of duplicate flow hardware. The reference electrode assembly is replaceable and front-loading, giving reduced polarization time on startup and a typical service life of up to 2 years.
Dual isolated 4-20mA outputs plus RS-485 Modbus, connected via an 8-pin connector, support integration with a PLC, SCADA, or third-party controller for industrial free chlorine monitoring and dosing control.
Why Use This
Fits Existing Installations
Ships without a flow reservoir kit, making it a direct fit for sites with an existing flow cell or in-line tee.
Built for Industrial Duty
The stainless steel body handles industrial and wastewater applications where a CPVC sensor body would not be appropriate.
Lower Maintenance
The replaceable, front-loading reference electrode gives a typical service life of up to 2 years.
Applications
- Industrial wastewater treatment — stainless steel body suited to demanding process environments
- Retrofit into existing flow cells or in-line tees — sensor-only configuration avoids duplicate flow hardware
- PLC/SCADA-integrated chlorine control — dual 4-20mA and RS-485 outputs via 8-pin connector
