อุปกรณ์วัด Control System (Conductivity Analog Controller with Direct Input from Potentiometric Probe 0.1 µS/cm resolution)
HI 943500D
Conductivity Analog Controller with Direct Input from Potentiometric Probe 0.1 µS/cm resolution
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.
