HI943500 are panel-mounted conductivity controllers designed for simplicity of use in a wide range of industrial process applications. Four different models are available with different measurement ranges, to satisfy any application requirements.

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.

No Need for a Transmitter

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.

Self-testing Diagnostics

Designed with built-in diagnostic functions to enable the user to check and troubleshoot the instrument. The checks performed are through the front panel keys and can be used to isolate the cause of malfunction.

Visual Indicator

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

Automatic Temperature Compensation

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

Friendly Interface

The instruments are designed with a standard DIN panel mount with membrane keypads on the front, a large LCD and with auto-diagnostic functions.

Robust Design

A removable, transparent splash-proof cover protects the front panel.
