  • Built-In Programmable Limit, Proportional (Pulse Length or Pulse Frequency) - ideal for precision process control applications

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

  • Readout in mg/L, pm or % saturation

  • Barometric and Salinity Automatic Compensation after manual input

  • 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

  • Choice of General Purpose or Low DO measurement for wider applications

  • 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

  • Large Dual Display shows DO 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
