Walchem ST-774 Pyxis Ultra-Low Luminescent Dissolved Oxygen Sensor & Flow Cell, Range 0.0-2,000 ug/L (ppb)

The Pyxis Lab® ST-774 is an ultra-low range dissolved oxygen (DO) sensor. It has a lower limit of detection 0.4 ppb (µg/L). design is based on the principle of fluorescence quenching. Therefore, determining the partial pressure of dissolved oxygen in water and incorporates Pyxis' advanced technology in the field of fluorescence detection. The ST-774 offers the robustness associated with optical DO sensor technology while achieving the ultra-low detection limit compatible to an amperometric DO sensor.
