Pyxis dissolved oxygen sensors

Pyxis ST-772 series

The Pyxis ST-772 series are optical luminescent dissolved oxygen (DO) sensors for measuring the dissolved oxygen content in water

This series of sensors incorporates Pyxis’ advanced technology in the field of fluorescence detection and uses blue/red light detection with excitation and reference light sources, offering a wide detection range and very low detection limit. The sensor also integrates temperature and pressure sensors, which can perform temperature and pressure compensation for the measurement of dissolved oxygen based on ambient environmental conditions present in the application of use.


Features

  • 0.004–20mg/L measurement range
  • No membrane replacement or electrolyte replacement
  • Simple DO cartridge replacement every 2 years
  • Built-in temperature & pressure sensor with automatic compensation
  • Accurate & stable measurement with ultra-low drift requiring no calibration for up to 2 years
  • Built-in transmitter without pre-amplifier or meter head
  • Dual outputs, both 4-20mA isolated signal & RS-485 modbus
  • Wireless calibration, diagnostics, data trend via uPyxis app when used with MA-CR
  • Slope calibration with air or air saturated water / zero calibrate with 5% sulphite solution or nitrogen gas
  • Submersible (ST-772 or ST-772P) or inline pipe tee (ST-772T or ST-772T-P) installation versions available
