hygrometer
C2/Low FrequencyTechnical/Scientific
Definition
Meaning
An instrument for measuring the humidity of the air or a gas.
A device, either analog or digital, used in meteorology, agriculture, industrial processes, and climate-controlled environments to determine the amount of water vapor present in the atmosphere.
Linguistics
Semantic Notes
The term is specific and unambiguous within its technical domain but is rarely used in everyday conversation. It belongs to a set of measuring instruments (cf. thermometer, barometer, anemometer).

Usage
Context Usage
Business
In HVAC or manufacturing quality control: 'All storage rooms must be equipped with calibrated hygrometers.'
Academic
In meteorology or materials science papers: 'Relative humidity was monitored continuously using a shielded hygrometer.'
Everyday
In hobbies like gardening or cigar storage: 'I got a little hygrometer for my greenhouse to keep an eye on moisture levels.'
Technical
In engineering specifications: 'The capacitive hygrometer has a response time of <5 seconds.'
Examples
By CEFR Level
- This is a hygrometer. It tells us how wet the air is.
- The weather station has a hygrometer to measure humidity.
- To ensure the archival documents are preserved correctly, the humidity is tracked with a precision hygrometer.
- Calibrating the hygrometer against a standard salt solution is essential for obtaining reliable data in the experiment.
Learning
Memory Aids
Mnemonic
Think: 'HYGROmeter measures HYGROscopic moisture' – both share the Greek root 'hygros' meaning wet.
Conceptual Metaphor
MEASUREMENT IS QUANTIFICATION; THE ATMOSPHERE IS A CONTAINER (of moisture).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'гигрометр' (correct translation) and 'гидрометр' (which is a hydrometer, for liquid density).
Common Mistakes
- Misspelling as 'hygrometre' (BrE spelling is still '-meter' for measuring instruments), 'higrometer', or confusion with 'hydrometer'.
