Morphology

altimeter = altitude (semi-transparent) = alti + meter

The word is readily interpretable as an instrument for measuring altitude, but it uses a specialized combining form and technical suffix.

Etymology

Altimeter breaks into two clear parts: alt- comes from a word meaning 'high', which you can see in altitude, and -meter means 'measure', like in thermometer. So an altimeter is an instrument that measures how high you are.
