Definition
Meaning
A laboratory instrument for measuring the strength of vinegar or acetic acid.
A device, typically a form of hydrometer or alkalimeter, used in analytical chemistry to determine the concentration of acetic acid in a solution.
Linguistics
Semantic Notes
The term is highly specialized and largely historical, having been supplanted by more modern analytical methods and instruments. Its usage today is primarily in historical texts or discussions of antique scientific apparatus.

British vs American Usage
Differences
No significant difference in usage or spelling.
Connotations
Carries the same technical, historical connotation in both varieties.
Frequency
Extremely rare in both British and American English, confined to very specific technical or historical contexts.

Examples
By CEFR Level
- The historical recipe mentioned using an acetometer, but today we would use a pH meter.
- In the 19th century, a vinegar producer might rely on an acetometer for quality control.
- The museum's collection of antique scientific glassware included a beautifully crafted but functionally obsolete acetometer.
- The researcher consulted a century-old manual describing the calibration of an acetometer using standard solutions of acetic acid.
Learning
Memory Aids
Mnemonic
Think 'ACETic acid + METER' (a meter for measuring acetic acid).

Common Pitfalls
Translation Traps (for Russian speakers)
- Может быть переведено как "ацетометр" (прямой калькированный заимствованный термин). Не путать с "ацидометр" (acidimeter) – более общий прибор для измерения кислотности.
Common Mistakes
- Misspelling as 'acitometer' or 'acetimetre'. Using it as a general term for any acidity measuring device, which is imprecise.

Frequently Asked Questions
No. An acetometer is a specific, often older, instrument for measuring acetic acid strength, while a pH meter is a modern electronic device that measures the acidity or alkalinity (pH) of any aqueous solution.
You are most likely to encounter it in historical texts, museums displaying scientific instruments, or in academic papers discussing the history of analytical chemistry or food preservation.
Newly manufactured acetometers are essentially unavailable as they are obsolete technology. They may occasionally be found for sale as antiques or collectibles.
It was largely replaced by more precise and general-purpose analytical techniques, most notably titration methods and later, electronic pH meters and chromatography.
