Can the thermometer still be used if its needle is knocked over?
Thread Content
In our daily use, generally after the pressure gauge is knocked over, it will not return to zero, the pressure will not be very accurate, and it cannot be used.； But can the thermometer still be used if it is knocked over? However, after recovering from the knock, it still feels a bit accurate, but I’m not sure yet. Does anyone know how the thermometer works? Can it still be used after being knocked over?
It is the same as a pressure gauge, as long as it is used after exceeding the range, it will be inaccurate.
The spring caused by tipping will undergo plastic deformation and will not be accurate.
Under normal circumstances, it cannot be used and must be scrapped.
It's definitely not accurate anymore, so don't use it anymore, and it's not very valuable.

It should damage the spring inside. It may still be usable, but it should be inaccurate and should be scrapped. By the way, anti-freeze and condensation must be done in winter. Freezing and condensation problems also have a great impact on the instrument and can easily damage the instrument.
