Description

The CDTX-90 Series Conductivity/ Resistivity Transmitter is designed for broad application and ease of setup and use. The unit can be used for conductance, resistance, or TDS signal transmission and display. Mounting can be accomplished in several options best tailored to your application requirements. Full microprocessor based electronics allow wide operating range, and long term signal stability due to the elimination or potentiometers, jumpers and dip switches.
