Description

The ST-765P Series are CPVC multi-parameter membrane-less sensors. Based on unique electrochemical principles to determine an oxidizer and pH content in water. These sensors incorporate Pyxis Lab® advanced technology in the field of bare-gold electrochemical detection. The ST-765P Series integrates an oxidizer measurement (Free Chlorine, Chlorine Dioxide, Sulfite, Ozone etc.) plus pH measurement. Both can perform temperature and pH compensation. For the measurement of the oxidizer based on the 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 & ISO-7393 guidelines.

The ST-765P Series sensors offer a replaceable, front-loading reference electrode assembly. Independently developed by Pyxis Lab®, eliminating the shortcomings associated with membranes and gel replacement while offering reduced polarization time on startup, offering an electrode life span potential of up to 2 years. The flat front-end is platform less prone to contamination or fouling and is easy to clean. The ST-765P Series sensor body is composed of CPVC and is well suited for clean water applications.

Details

The ST-765P Series offer (2) 4-20mA and RS-485 Modbus outputs and is Bluetooth® 5.0 enabled when used with the MA-CR Bluetooth® adapter. The world’s first four-electrode composite sensor that provides three measured parameters including Free Chlorine or Chlorine Dioxide, pH and Temperature with one sensor RS-485 Modbus output. The ST-765P is the best choice for potable water, secondary water supply, domestic water, decorative water and other clean water applications.

Features

  • Real-Time pH + Oxidizer (0-5ppm) Detection
  • Dual 4-20mA Outputs (Oxidizer+ pH) and RS-485
  • Bluetooth® Enabled when used with MA-CR Adapter Wireless for uPyxis Calibration
  • Integrated RTD & pH Compensation to pH 9.0 of the Oxidizer Value
  • Replaceable EH-765 Reference Electrode Assemble for Simple Maintenance
