Electrical conductivity (electrical conductivity) measurement module

Surveillance; High precision measurement; Proofreading support; DC power supply; DIN rail mounting; No water quality information provided; Analog output; Measurement range is switchable.

This is a slim electrical conductivity (conductivity) measurement module.
It features an analog output (4-20mA) and allows for dual output of water quality and water temperature.
Its slim and compact design allows for space-saving installation in control panels and other applications.
The measurement range can be switched using the DIP switches on the front panel (0-4/0-20/0-200/0-400μS/cm).
It can be used in a wide range of industries and applications, from measuring pure water and RO water to managing the concentration of cooling water and circulating water.
Please use it in combination with the 7701 sensor series.
