An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose. The altimeter uses the changes in atmospheric pressure to determine the changes in altitude.
Barometer is the device used for measuring atmospheric pressure.Whereas,altimeter is the instrument that measures the altitude of the land surface or of any object, such as an â¦ airplane.he principals of design for the Barometer and Altimeter are the same. A sealed capsule expands and contracts with changes in air press â¦ ure, this movement is then changed to the movement of a dial to get a scaled reading.
