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 additional temperature and pressure sensors, which can perform temperature and pressure compensation for the measurement of dissolved oxygen in the system.
Features
0.004–20 mg/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
