For the solutions listed above, the device can determine the sub-
stance concentration from the measured conductivity and tempera-
ture values in % by wt. The measurement error is made up of the
sum of measurements errors during conductivity and temperature
measurement and the accuracy of the concentration curves stored in
the device. We recommend to calibrate the device together with the
sensor, e.g. directly to concentration using the CAL_CELL method. For
exact temperature measurement, you should perform a temperature
probe adjustment. For measuring processes with rapid temperature
changes, a separate temperature probe with fast response should be
used.
When measuring processes such as dilution or intensification of CIP
solutions (Clean-In-Place), it is helpful to switch between the param-
eter sets for measuring the process medium and for measuring the
CIP solution.
For specification of a concentration solution for conductivity
measurement, see page 53.
