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.
ST-600 Series High Concentration Disinfection Sensors
The Pyxis ST-600 Series inline sensors are designed for use in qualitative measurement of real-time mass/mass concentration of Chlorine in Sodium Hypochlorite from manufactured liquid chemical concentrate (bleach) or diluted liquid through electrolysis, as well as in-situ Chlorine Dioxide (ClO2) generation. Unlike typical amperometric sensors for disinfection liquids in ppm level, the ST600 Series inline probes directly measure the optical density of the Bleach or Chlorine Dioxide solution in percentage (%) levels without dilution using a UV light source.
