Pyxis ST-600 Series Inline Disinfection + Temperature Sensors

Description

DESCRIPTION
The Pyxis ST-600 series inline probes measure the real-time mass/mass concentration of Chlorine in Sodium Hypochlorite Bleach and Chlorine Dioxide (ClO2) in Solution. Unlike typical amperometric sensors for disinfection liquids in ppm level, the ST-600 series inline probes directly measure the optical density of the Bleach or Chlorine Dioxide solution in percentage level without dilution using a UV light source. The ST-600 series probes have a built-in reference light source and a reference light detector in addition to the main light source and main light detector. This configuration ensures a long-term stable measurement of the disinfectant concentration. These probes featuring an expanded detection range and an RTD temperature compensated output signal, allowing the user to measure higher concentrations of industrial Bleach / ClO2 respectively and to obtain a temperature measurement, useful when required to consider the impact of atmospheric temperature conditions on variable concentration readings. Typical Applications • Biocontrol for industrial water • Industrial Oxidizer Generation (ie. Hypochlorite /Monochloramine / ClO2) • Swimming pool and SPA • Hospital • Pulp & Paper
