Cleaning the probe
Depending on the application, contamination or buildup can accumulate on the probe. A thin,
even layer only influences measurement slightly. Thick layers can dampen the signal and then
reduce the measuring range. Severe, uneven buildup, adhesion e. g. through crystallization,
can lead to incorrect measurement. In this case, we recommend that you use a non-contact
measuring principle, or check the probe regularly for soiling.
