It's extremely unwise to remove the protection tip of our hygrometry
probes as the sensitive element is very fragile even to light contacts.
However, if you have to remove the protection tip, take all possible
precautions and avoid any contact with the sensitive element.
To remove the protection tip, unscrew it or unclip it.
