Conductivity Controller

industrial instruments homepage | buy or view price | manual

  • 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 Setup Menu in matching the functions to suit specific operation
  • Tri-Level Password Protection against authorized tampering
  • Non-Volatile Memory retains all stored measurement parameters and calibration data
  • Selectable Cell Constant (0.01, 0.1, 1.0, 10.0) to cater for different applications for more accurate measurements
  • Two contact relays and 1 Alarm Relay with independent timer control
  • Hysteresis Band Protection against rapid control switching of relays from wear and tear
  • Temperature Coefficient for more accurate measurement with a pure water compensation option available to automatically compensate for linearity in linear/pure water applications
  • Line Resistance Compensation against intrinsic cable resistance for longer cable connection
  • Choice of Temperature Sensor Pt100/Pt1000 with 2-wire or 3-wire temperature input selection
  • Electrode Diagnosis can be obtained after each successful calibration with cell characteristics displayed, useful for tracking the cell efficiency
  • Scalable  0/4..20 mA transmitter isolated output for use to maximize the resolution on the chart recorder
  • IP54 rated front panel against dust and accidental water spills
  • Installation and wiring are easily performed with detachable plug-in connectors
