Definition
- Adjective:
- Containing no liquid or actuated without the use of liquid: Describes a device or mechanism that operates without relying on fluids.
- Noun:
- Aneroid barometer: A type of barometer that measures atmospheric pressure using a sealed, flexible metal box from which most air has been removed, rather than using a liquid column.
Usage Examples
- Adjective:
- The aneroid mechanism is less fragile than a mercury-based one.
- Many modern pressure gauges use an aneroid design.
- Noun (Aneroid barometer):
- The hiker checked his aneroid to predict the weather.

Advanced Usage
- Technical Context: In meteorology and aviation, "aneroid" specifically refers to instruments that measure pressure mechanically, crucial for altimeters and weather forecasting equipment.

Variants and Related Words
- Aneroid barometer (n): The full term for the device, often shortened to "aneroid."
- Aneroid capsule (n): The key sealed metal component inside an aneroid barometer that expands and contracts with pressure changes.
Synonyms
- Adjective: Dry, non-liquid, mechanical.
- Noun (for the device): Pressure gauge, barometer (when context is clear).
Notes on Meaning
- The term is almost exclusively used in technical contexts related to pressure measurement. The adjective form is rarely used outside of describing such instruments (e.g., aneroid gauge, aneroid cell).
