Structure and function

2.1

Structure

The following conductivity probes can be used in conjunction with Multronic conductivity
module 255177. (material numbers see chap.
Fig. 2.1
Measuring cell installed
in PVC-flow fitting
2.2

Temperature compensation

The conductivity changes in dependence on the temperature of the solution that is to be
measured. The influence of the temperature on the result of the measurement is
compensated through the temperature sensor that is integrated into the measuring cell.
The temperature compensation factor can be adjusted in the device between 0%/K ad
5%/K in stages of 0,01%/K.

Conductivity Measuring Module (contact measurement)
Measuring cell installed
in PVC immersion fitting
Temperature compensation factor Tkα for the solution to be measured must be
individually determined and incorporated into the measuring parameters (see Section
4.2), in order to obtain the most accurate possible reading. Incorrect values for Tkα
(including Factor 0.0 %/K) can result in significant deviation in the measured
readings!
