5.10 Conductivity Monitor
Introduction
This section describes how to perform Conductivity Monitor calibrations and edit the
Cell constant settings.
In this section
This section contains the following sub-sections:

98 5.10.3 Conductivity flow cell calibration
Description
The Conductivity Monitor consists of a conductivity cell with two parallel cylindrical
electrodes positioned in the flow path of the cell. One of the electrodes has a temperature
sensor for measuring the temperature of the liquid in the cell.
Description Parameter
The Cell constant is a characteristic of the conduc-
tivity cell, defined as the ratio of the distance be-
tween the electrodes and the area of an electrode. Cell constant
(Set cell const)
Ambient temperature variations influence the
conductivity. In Handbooks and other documen-
tation, the conductivity values are most often
given at a certain Reference Temperature (20°C
or 25°C). To compare with those values, the actual
conductivity has to be re-calculated to conductiv-
ity at the reference temperature. Reference temperature
