OXIPANEL™ IK-765 Series Oxidizer + pH Inline Analyzers for Drinking & Clean Water

The IK-765 Series are dual-parameter inline water analyzers designed as a ‘Turn-Key’ monitoring solution for clean water applications including drinking water networks, secondary water supply and decorative/swimming water applications. The IK-765 series offers accurate, real-time measurement, display and data-logging of Free Chlorine, pH and Temperature. Utilizing proprietary Pyxis Lab® smart sensor technology coupled with a Pyxis UC-50 micro display and data logging terminal, the IK-765 series is offered in a convenient and easy to integrate panel mounted format for rapid installation and simple maintenance.

The IK-765 series analyzer is offered in two sensor formats. The ST-765SS series sensors measure Free Chlorine or Chlorine Dioxide, pH and temperature of the sample water. This sensor design is membrane-free and based on unique principles and incorporates Pyxis’ advanced technology in the field of bare-gold electrochemical detection. The ST-765SS-FLC (Free Chlorine + pH) and 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. Each IK-765 panel is also provided with the FR-50 Flow Reservoir and UC-50 micro display/data logging terminal prewired to the ST-765SS series sensor 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 wet chemistry methodology as high as pH 9.0 and meets EPA-334.0 and ISO-7393 compliance.

Typical Applications

• Drinking Water
• Domestic Water
• Secondary Water Supply
• Sanitary Water
• Decorative Water
• Food & Beverage Process Water
• RO Feedwater

Features

The ST-765SS-FCL (Free Chlorine + pH/Temperature) and ST-765SS-CLO (Chlorine Dioxide + pH/Temperature) are three-parameter composite sensors used for the measurement residual free chlorine or chlorine dioxide, pH and temperature in compliance with USEPA 334.0 and ISO-7393 guidelines. The sensors advanced PCB offers built-in temperature and pH parameter compensation (up to pH 9.0) algorithms eliminating the need for a supplemental pH sensor and controller. Unique Bare-Gold electrode technology for residual chlorine measurement eliminates membranes and electrode solution replenishment commonly associated with conventional sensors. The ST-765SS Series has a uniquely designed flat bubble pH electrode design for reduced fouling potential. Reduce your maintenance and cost versus colorimetric chlorine measurement or conventional electrochemical sensors by utilizing Pyxis replaceable Electrode Head (EH-765) for this sensor allowing for years of reliable service. The ST-765SS Series may be calibrated in-situ after cleaning via DPD Free Chlorine or Chlorine Dioxide wet chemistry test measurement of active sample.

The FR-50 Single-Sensor flow reservoir provides sample calming for dissipation of air-bubbles and settling of suspended solids, foam or other impurities commonly observed in drinking water influent. This unique flow reservoir design results in the highest level of oxidizer resolution on the market and greatly extends the maintenance cycle of the sensor while providing a large buffer capacity to mitigate pressure fluctuations. The minimum inlet pressure of FR-50 flow reservoir is only 7.5 psi (0.05mpa) making it highly suitable for the end of pipe networks and secondary supply influent sampling. One FR-50 is provided with the purchase of each ST-765SS Series sensor and comes equipped with inlet PRV and Rotameter for the recommended flow range of 600–1,800 mL/minute. The FR-50 outlet flow and sewer overflow lines should be diverted to drain or the inlet of the pretreatment system for those desiring NSF compliance

• Simple sensor removal and replacement. The ST-765SS Series sensors are connected to the display/data logger via RS-485 modbus (RTU) allowing for integrated sensor calibration interface and diagnostics within the display screen.
• Convenient and simple to install Back-Panel (IK-765) for rapid and easy installation. Truly a plumb and power to go platform with intense factory setup, testing and sensor calibration prior to shipment.
• UC-50 micro display/data logger interface with sensor calibration integrated. Display/data logger offers 1x 4- 20mA I/O as well as RS-485 with remote diagnosis and parameter adjustment. Pyxis CloudLinkTM 4G Gateway available as an optional accessory.
