Key benefits include: Real-time pH + oxidizer (0-5ppm) detection, dual 4-20mA outputs (oxidizer + pH) and RS-485 (Modbus RTU), optional auto-brushing flow reservoir for dirty water applications, integrated RTD & pH compensation to pH 9.0 of the oxidizer value, and simple maintenance with a replaceable reference electrode assembly.
The Pyxis ST-765SS Series are stainless steel multi-parameter membrane-less sensors 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’ advanced technology in the field of bare-gold electrochemical detection. Offered in two formats, the ST-765SS-FCL (free-residual chlorine + pH) and the ST-765SS-CLO (chlorine dioxide + pH) 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. Typical applications for this sensor include potable water, secondary water supply, industrial water, domestic water, and cooling tower water.
