  • User-Customization through Advanced Setup Menu offers flexibility in matching the controller's functions to suit individual's specific requirement

  • Automatic Calibration with Auto-Buffer Recognition eliminates mistakes during calibration

  • Symmetrical Mode Operation eliminates electronic noise problems when used with solution ground

  • One-Point Online Calibration without shutting down the line

  • Hold Relay for use with float switches/flow switches and other controllers as a failsafe function

  • 0 to 2000 Second Time Delay Adjustment on control and alarm delays

  • Galvanically Isolated Scaleable 0-20/4-20 mA Outputs for pH/ORP

  • Hysteresis Band Protection against rapid control switching of relays from wear and tear

  • Non-Volatile Memory retains all stored parameters and calibration data even if power fails

  • Large Dual Display shows pH (or ORP) with temperature simultaneously - features clear multiple icons, set points, and status messages

  • Choice of Temperature Sensor Pt100/Pt1000 with 2-wire or 3-wire temperature input selection

  • Easy Installation and Wiring with detachable plug-in connectors
