CT100S Digital Conductivity Transmitter

CT-100S Conductivity TransmitterDescription

Electronet Series CT-100S are high-performance conductivity transmitters designed for a wide range of industrial applications.
They accept input from conductivity electrodes with cell constants 0.01 / 0.1 / 1, and convert the conductivity signal into a standard 4–20 mA output.
The unit provides clear on-line indication through a backlit LCD. Span and zero adjustments are easily accessible, ensuring user-friendly operation and quick calibration.
