Concentration Measurement
Measuring Ranges
For the solutions listed above, the device can determine the substance concen-
tration from the measured conductivity and temperature values in % by wt. The
measurement error is made up of the sum of measurements errors during con-
ductivity 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, use a separate tempera-
ture probe with fast response.
