Pyxis ST-774 Inline Sensor

Pyxis ST-774

The ST-774 measures the oxygen partial pressure that is at equilibrium with the dissolved oxygen in water governed by Henry’s law (DO/ppb = K PO2)

The Pyxis Lab® ST-774 is an ultra-low range dissolved oxygen (DO) sensor with a lower limit of detection 0.4 ppb (µg/L). Our design is based on the principle of fluorescence quenching to determine 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.
