Hanna Instruments EC Analog Controller

These controllers allow 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
Direct connection of a potentiometric conductivity probe (HI-7638) with a cable up to 20 meters long, without using a 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 HI-7638 probe with built-in temperature sensor.
The front panel is protected behind a transparent splash-proof cover.
