Barometric Altimeter

A barometric altimeter is a device used to measure altitude, or height above sea level, by detecting changes in atmospheric pressure. As you go higher, the air pressure decreases. The altimeter measures this pressure change and translates it into altitude, providing information about your elevation. It’s commonly found in aircraft, hiking equipment, and weather stations. To maintain accuracy, an altimeter may need calibration to account for weather changes, as variations in atmospheric pressure can affect readings. Overall, it’s a vital tool for navigation and safety in various outdoor and aviation activities.
