Pyxis ST-606 Inline Temperature + Acidified Sodium Chlorite (ASC) Sensor
Inline temperature + acidified sodium chlorite (NaClO2) sensor (0-1,200ppm), 254nm. Dual 4-20mA + RS-485, 7-pin.
Pyxis ST-606 Inline Temperature + Acidified Sodium Chlorite (ASC) Sensor
The Pyxis ST-606 is an inline, temperature-compensated sensor that measures acidified sodium chlorite (ASC / NaClO2) using 254nm detection, covering 0-1,200ppm. It provides dual 4-20mA analog outputs plus RS-485 Modbus communication through a single 7-pin connector, enabling direct integration into ASC-based disinfection monitoring systems.
Description
The Pyxis ST-606 is an inline, temperature-compensated sensor built to measure acidified sodium chlorite (ASC / NaClO2) concentration using 254nm optical detection, covering a range of 0-1,200ppm. It is designed for facilities using ASC-based disinfection chemistries that require accurate, continuous inline measurement.
The sensor automatically compensates for temperature variation in the process stream, keeping ASC readings consistent as water conditions change. It outputs via dual 4-20mA analog signals plus RS-485 Modbus, delivered through a single 7-pin connector for simplified field wiring.
With both analog and digital communication built in, the ST-606 can feed conventional analog controllers as well as networked PLC/SCADA systems, enabling direct integration into existing ASC-based disinfection monitoring setups.
Why Use This
Accurate ASC Concentration Monitoring
254nm-based detection covering 0-1,200ppm, with temperature compensation, delivers reliable acidified sodium chlorite readings for antimicrobial water treatment programs.
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
- ASC (acidified sodium chlorite) disinfection monitoring — continuous inline measurement from 0-1,200ppm
- Integration into existing ASC-based disinfection monitoring systems
- PLC/SCADA-based process control — RS-485 Modbus enables networked automation
