The Pyxis ST-765 Series Oxidizer + pH Sensor is a multi-parameter membrane-less sensor based on unique electrochemical principles to determine numerous oxidizers including free-residual chlorine and chlorine dioxide plus pH and temperature of water. These sensors incorporate Pyxis' technology in the field of bare-gold electrochemical detection. Offered in two formats: free-residual chlorine + pH, and the chlorine dioxide + pH, which can simultaneously compensate for temperature and pH in the measurement of oxidizer based on real-time conditions present in the application of use. This unique internal compensation results in a highly accurate oxidizer measurement consistent with DPD wet chemistry methodology as high as a pH of 9.0+ and is compliant with USEPA – 334.0 and ISO-7393 guidelines.  

The ST-765 series sensors offer 2x 4-20mA and RS-485 Modbus outputs and is Bluetooth 5.0 enabled when used in conjunction with the MA-CR Bluetooth Adapter. This four-electrode composite sensor provides three measured parameters including oxidizer, pH and temperature with one sensor equipped with fully integrated 2x 4-20mA and RS-485 Modbus outputs. ST765SS is the best choice for potable water, secondary water supply, industrial water, domestic water, decorative water and other clean water applications.
