This conductivity analyzer has been designed for continuous
monitoring and control of conductivity. It is available in wall-/
pipe-mount or panel-mount versions and can be used with
either one or two sensors, each with a temperature input
channel. When used with two sensors, readings can be
compared to produce a range of extrapolated values.

When making temperature compensated measurements, the
sample temperature is sensed by a resistance thermometer
(Pt100 or Pt1000) mounted in the measuring cell.

Analyzer operation and programming are performed using five
tactile membrane keys on the front panel. Programmed
functions are protected from unauthorized alteration by a five-
digit security code.
