Full Description Specification

The controller allows the direct connection of a potentiometric conductivity probe (HI 7638) with a cable up to 20 meters long, without using any transmitter.

  • Automatic temperature compensation ensures fast, accurately compensated readings even during sudden temperature fluctuations
  • Four different models are available with different measurement ranges
  • Displays values on the easy to read LCD with backlighting

Four different models are available with different measurement ranges, to satisfy any application requirements.

The output configuration for connecting a recorder or a PLC can be chosen between 0-20 or 4-20 mA.

The LED on the front panel indicates the operating status of the controller.

The automatic temperature compensation (ATC) is performed directly by the HI-7638 probe with built-in temperature sensor.

The front panel is protected behind a transparent splash-proof cover.
