What does aneroid mean?
A barometer that measures atmospheric pressure using a column of liquid, typically mercury, and a flexible metal or glass tube that is not sealed at the top, allowing the liquid to expand or contract with changes in pressure.
Example
"The aneroid barometer on the wall indicated a sudden drop in pressure, signaling an approaching storm."
