HI943500D Conductivity Controller, 0 to 199.9 uS/cm with 4 to 20mA

Direct connection of up to 20 m (66′) without needing to amplify the signal to the HI 7638 probe

• Automatic diagnostic controls
• Available in four models, each with a different measurement range
• Operational mode LED indicators
• Automatic Temperature Compensation with HI 7638 potentiometric conductivity probe with built-in temperature sensor
• Transparent splash-proof cover included

 

These controllers allow direct connection of a potentiometric conductivity probe
(HI 7638) with a cable up to 20 m long, without needing a transmitter to amplify the signal.

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.
