Used calibration solution
Dispose of the used calibration solution. For more
information: see calibration solution safety data
sheet.
Two test containers with a calibration solution are required for cali‐
bration. The fluoride content of the calibrating solutions should be
at least 0.5 ppm F
apart from each other. The sensor should be
-
rinsed thoroughly with fluoride-free water when changing the cali‐
brating solution.
