vaporimeter
Very Rare / TechnicalTechnical / Scientific
Definition
Meaning
An instrument for measuring the vapor pressure or the proportion of vapor in a mixture.
A specialized device, often used in scientific and industrial contexts (e.g., petrochemical, pharmaceutical), to determine the volatility of liquids or the concentration of a vapor in air.
Linguistics
Semantic Notes
Belongs to a category of scientific instruments ending in '-meter' (e.g., barometer, thermometer). Its meaning is specific and literal, with no figurative usage.
Dialectal Variation
British vs American Usage
Differences
No significant lexical difference. Spelling may follow regional conventions (e.g., 'vapour' in British texts influences related compounds, but 'vaporimeter' is the standard spelling for the instrument).
Connotations
None; purely denotative technical term.
Frequency
Equally rare in both dialects, confined to technical literature.

Learning
Memory Aids
Mnemonic
Think: 'VAPOR' + 'METER' (a meter for vapor). It measures vapor, just like a thermometer measures thermal heat.
Conceptual Metaphor
MEASUREMENT IS QUANTIFICATION (of a gaseous state).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'испаритель' (evaporator) or 'парометр' (a non-standard direct calque). The correct Russian term is often 'паровой манометр' or 'прибор для измерения давления пара'.
Common Mistakes
- Misspelling as 'vapourimeter' in any formal technical English. Incorrectly using it to mean a humidifier or a device that *creates* vapor.

FAQ
Frequently Asked Questions
No, it is a highly specialized technical term used only in specific scientific and industrial fields.
A vaporimeter measures vapor pressure or concentration of a specific vapor in a mixture. A hygrometer measures relative humidity, i.e., the amount of water vapor in the air.
No, it is solely a noun. There is no standard verb form 'to vaporimeter'.
It is pronounced /ˌveɪpəˈrɪmɪtər/ in American English, with the primary stress on the third syllable 'rim'.
