The ST-772 dissolved oxygen (DO) sensor is based on the principle of fluorescence quenching to determine the dissolved oxygen content in water. It incorporates Pyxis’ advanced technology in the field of fluorescence detection and uses dual light source detection technology with excitation and reference light sources, offering a wide detection range and low detection limit. The sensor 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.
