Pyxis ST-712 Inline pH + ORP Analyser
Inline pH + ORP analyser (0-14 / +1,500mV). Dual 4-20mA + RS-485, 7-pin.
Pyxis ST-712 Inline pH + ORP Analyser
The Pyxis ST-712 is a combined inline pH and ORP analyser for process and treatment water monitoring, covering a 0-14 pH range and up to +1,500mV ORP. It provides dual 4-20mA analog outputs plus RS-485 Modbus communication through a single 7-pin connector, consolidating two measurements into one inline sensor.
Description
The Pyxis ST-712 is a combined inline pH and ORP analyser for process and treatment water monitoring, covering the full 0-14 pH range and ORP up to +1,500mV in a single instrument. It consolidates two commonly paired measurements into one inline sensor, reducing the number of separate instruments needed at a monitoring point.
The analyser provides dual 4-20mA analog outputs — one for each measurement — plus RS-485 Modbus communication, all delivered through a single 7-pin connector for simplified field wiring.
This combined-parameter design suits water treatment operations that track both pH and ORP together, allowing direct integration into existing control systems while cutting down on installation complexity compared to running two separate sensors.
Why Use This
Two Measurements, One Sensor
Combining pH (0-14) and ORP (up to +1,500mV) in a single inline unit reduces the number of tap points and sensors needed for process water monitoring.
Flexible System Integration
Dual 4-20mA analog outputs combined with RS-485 Modbus let the sensor communicate with both analog controllers and networked control systems through one 7-pin connector.
Applications
- Combined pH and ORP monitoring in process water treatment systems
- Treatment water quality monitoring where both parameters are tracked together
- PLC/SCADA integration for consolidated pH/ORP control loops
FAQ
What does the ST-712 measure?
It measures both pH (0-14 range) and ORP (up to +1,500mV) from a single inline sensor.
Does it provide separate signals for pH and ORP?
Yes, it provides dual 4-20mA analog outputs — one for pH and one for ORP — plus RS-485 Modbus communication.
What connector does it use?
A single 7-pin connector carries both analog outputs and the Modbus signal.
What is the benefit of a combined pH/ORP sensor versus two separate units?
Consolidating both measurements into one inline sensor reduces the number of instruments and connections needed at a single monitoring point.
