C 7635 E.Conductivity analyzer

The controller use 2-electrodes conductivity cells with K = 0.10 - 1.00 - 10.0  in various selectable ranges. It provides manual and automatic temperature compensation, if an RTD Pt100 or Pt1000 is connected. When the RTD is connected, the instruments provides the temperature reading.
