Walchem ST-773 Pyxis Luminescent Dissolved Oxygen Sensor, 0.004-20 mg/L, Submerged/Inline Installation, CPVC

The Pyxis Lab® ST-773 optical luminescent dissolved oxygen sensor is based on the principle of ‘fluorescence quenching' to determine the dissolved oxygen content in water. It incorporates advanced technology in the field of fluorescence detection. Uses dual Blue/Red light detection technology with excitation and reference light sources, offering a wide detection range and very low detection limit.

The sensor also integrates a temperature sensor for compensation of the measurement of dissolved oxygen based on environmental conditions. The ST-773 offers an easily replaceable, front loading DO membrane cap that has been independently developed by Pyxis Lab®, with a typical service life of up to 2 years. So, this unique membrane cap design incorporates a black microporous PTFE membrane material designed to provide extreme scratch resistance, extended life span and simple replacement.
