1. Aneroid readings must be adjusted for temperature and humidity.

2. Any aneroid gauge must be calibrated frequently.

3. An instrument for determining elevation, especially an aneroid barometer used in aircraft that senses pressure changes accompanying changes in altitude.

4. An aneroid is a sealed bellows which is sensitive to changes in atmospheric pressures.

5. An aneroid is a sealed bellows which is sensitive to changes in atmospheric pressure.

6. Fixed cistern barometers are used as a standard for checking aneroid barometers.
