CALIBRATION:
All
All
UPW testers are factory-calibrated with freshly
prepared low-conductivity solutions. Infact , due to
their high instability, calibration solutions in the
UPW range (below 2 µS/cm) can not be supplied
with the meter.
However, if your meter needs to be recalibrated, use
a 1.500 µS/cm solution prepared by a qualified
laboratory and keep it airtight.
