These controllers allow the direct connection of a potentiometric conductivity probe (HI7638) with a cable up to 20 meters long, without using any transmitter.
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 HI7638 probe with built-in temperature sensor.
The front panel is protected behind a transparent splash-proof cover.
