Concentration Measurement
For the solutions listed above, the device can determine the substance concen-
tration from the measured conductivity and temperature values in % by weight.
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 calibrating the device together with
the sensor, e.g., directly to concentration using the CELL CONST. method. For exact
temperature measurement, you should perform a temperature probe adjustment.
