acidometer
RareTechnical / Scientific
Definition
Meaning
A device or instrument used to measure the strength or concentration of an acid.
A type of hydrometer or other analytical instrument specifically calibrated for determining acidity, often used in chemistry and industrial processes.
Linguistics
Semantic Notes
A highly specialized term belonging to scientific nomenclature. It is not a general term for a pH meter (which is more common), but rather denotes instruments, often older or specific types, designed for acid concentration measurement.
Dialectal Variation
British vs American Usage
Differences
No significant usage differences. The term is equally rare and technical in both varieties.
Connotations
Purely technical; may imply older, industrial, or specific laboratory contexts.
Frequency
Extremely low frequency in both varieties, found primarily in historical or highly specialized technical texts.

Usage
Context Usage
Business
Unused in general business. Might appear in procurement for specific chemical or manufacturing industries.
Academic
Used in historical chemistry texts or very specialized papers on analytical methods.
Everyday
Never used.
Technical
Primary domain. Used in chemistry, chemical engineering, metallurgy, and industrial process descriptions.
Examples
By CEFR Level
- The scientist checked the liquid with a special tool.
- For the experiment, we needed to measure the acid concentration using an acidometer.
- The vintage acidometer, calibrated for sulfuric acid, provided surprisingly accurate readings compared to the digital pH probe.
- Industrial processes in the 19th century often relied on a simple acidometer for quality control in vitriol production.
Learning
Memory Aids
Mnemonic
Think: ACID-O-METER. It meters (measures) acid, just like a thermometer measures heat.
Conceptual Metaphor
A GAUGE FOR CORROSIVENESS. The instrument quantifies a potentially harmful/ reactive property.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'pH-meter' (pH-метр), which is the far more common modern instrument. 'Acidometer' is a more specific, older term.
- May be incorrectly parsed as 'кислотомер', which is a direct calque but not a standard Russian term; the standard is 'pH-метр' or 'ацидиметр'.
Common Mistakes
- Misspelling as 'acidmeter' or 'acydometer'.
- Using it as a general synonym for 'pH meter'.
- Incorrect pronunciation stress on the first syllable (/ˈæs.ɪ.dəʊ.miː.tə/).

Frequently Asked Questions
Not exactly. While both measure acidity, a pH meter gives a logarithmic pH value, whereas an acidometer is often a specific type of hydrometer that gives a direct measure of acid concentration (e.g., percentage by weight).
Primarily in historical texts, industrial chemistry, metallurgy (e.g., pickling baths), and specialized analytical chemistry. It is not common in modern general laboratory language.
"pH meter" is the vastly more common general term. For specific concentration measurements, "titration" is the standard analytical method, not a single instrument called an acidometer.
Yes, 'acidimeter' is a valid, equally rare synonym. The choice between '-meter' and '-meter' is variable in scientific instrument names.
