The IK-765-B Series are dual-parameter inline water analyzers specifically designed as a ‘Turn-Key’ monitoring solution for challenging water applications including:

  • Cooling Water
  • Food & Industrial Process Water
  • Raw Water
  • Treated Wastewater, Effluent Applications

The IK-765SS-B series are dual-parameter inline water analyzers specifically designed as a ‘Turn-Key’ monitoring solution for challenging water applications including cooling water, food and industrial process water, raw water, and treated wastewater effluent applications.  It offers highly accurate, real-time measurement, display, and data-logging of up four oxidizer measurement formats as well as pH and temperature utilizing proprietary Pyxis Lab smart sensor technology, coupled with a Pyxis UC-50 micro display and data logging terminal. The IK-765SS-B also incorporates a uniquely designed automated mechanical brush flow assembly which is directly controlled via the UC-50 display to maintain optimum sensor electrode cleanliness in the most challenging of system water. Offered in a convenient and easy to integrate panel mounted format for rapid installation and simple maintenance.

The IK-765SS-B series analyzer is offered in four sensor formats depending on the desired oxidant being measured.  The panel design is equipped with the propriety Pyxis ST-765SS Series smart sensors based on application needs.  The ST-765SS series sensors measure Free Chlorine (FCL), Total Chlorine (TCL), Bromine (Br), Chlorine Dioxide (CLO), or Monochloramine (NCL). In addition to pH and temperature of the sample water.  This Pyxis sensor design is membrane-free and based on unique principles incorporating Pyxis’ advanced technology in the field of bare-gold electrochemical detection. The ST-765SS-FLC (Free Chlorine + pH), ST-765SS-TCL (Total Chlorine + pH), ST-765SS-Br (Bromine + pH) ST-765SS-CLO (Chlorine Dioxide + pH), and ST-765SS-NCL (Monochloramine + pH) sensors measure the oxidant level and pH simultaneously while performing temperature and pH compensation for the measurement of oxidant based on conditions present in the application of use.

Additional Features

Each IK-765SS-B panel is also equipped with the FR-300-PLUS mechanical brushing flow assembly to ensure constant electrode cleanliness.  The UC-50 micro display/data logging terminal is prewired to the ST-765SS. In RS-485 Modbus format with fully integrated sensor diagnostics and calibration interface.  This unique platform with internal sensor compensation results in a highly accurate oxidizer measurement. Consistent with DPD/Indophenol wet chemistry methodology as high as pH 9.0+ and meets EPA-334.0 and ISO-7393 compliance.
