  • Ten Selectable Conductivity Measurement Ranges in one controller via its IP54 front panel. High-level accuracy of ±1% of full scale can be obtained with appropriate cells and correct temperature coefficient

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

  • Choice of Cell Constant (0.01, 0.1, 1.0, 10.0) for accurate control in any solution

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

  • Two Level Password Protection prevents un authorized tampering with settings

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

  • Galvanically Isolated Scalebale 0-20/4-20 mA Outputs

  • Wash Contact Relay controls electrodes cleaning systems at desired duration and frequency

  • Adjustable Hysteresis (Dead Band) prevents rapid contact switching near set point

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

  • Line Resistance Compensation against intrinsic cable resistance for longer cable connection

  • Large Dual Display shows measurement 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
