Cleaning

Housing:
Make sure that the housing surface and seals are resistant to cleaning agents.
Probe:
Depending on the application, buildup of contamination or soiling can form on the probe.
A high level of material buildup can affect the measurement result.
The regular cleaning of the probe is recommended if the medium tends to create a high
level of buildup.
Make sure that the insulation of the probe is not damaged if hosing down or during
mechanical cleaning.
