Conductivity Calibration

PCE-PWT 10 pocket salinity tester allows up to 3 points calibration in the conductivity mode. To
ensure higher accuracy, we recommend that you perform 3 points calibration or select a standard
value close to the sample value you are measuring. The tester will automatically detect these
conductivity standard solutions and prompt the user to calibrate the meter. When the calibration
is done, all new calibration values will automatically override existing data. The following table
shows acceptable conductivity range of calibration solution for each measuring range.
MEASURING RANGE
0~20µS/cm
20~200µS/cm
200~2000µS/cm
2~20mS/cm
Ensure that you use fresh conductivity standard solution during the calibration. Do not reuse
calibration solutions as it may be contaminated and affect the calibration and accuracy of
measurement.
