lactometer
C2Technical / Scientific
Definition
Meaning
An instrument for measuring the specific gravity (and thus the purity or richness) of milk.
A hydrometer specifically calibrated for milk, used in dairy science and quality control to detect adulteration (e.g., with water) and determine cream content.
Linguistics
Semantic Notes
Highly specific term, primarily used in dairy science, veterinary medicine, and historical food safety contexts. Not part of general vocabulary.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. The term is equally technical and rare in both varieties.
Connotations
Technical, precise, antiquated (modern industrial labs use more sophisticated electronic analyzers).
Frequency
Extremely low frequency in both regions, confined to specialist texts and historical descriptions of dairy farming.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'лактометр' (laktometr) – a direct equivalent, but a very low-frequency word even in Russian technical contexts. No false friends.
Common Mistakes
- Misspelling as 'lactameter'.
- Confusing it with a general hydrometer or a thermometer.

FAQ
Frequently Asked Questions
In modern industrial dairy processing, it has largely been replaced by more advanced electronic or optical analyzers, but it may still be used in small-scale, traditional, or educational settings.
A lower-than-expected reading indicates that the milk has been diluted (usually with water), as pure milk has a higher specific gravity.
There is no practical difference; 'galactometer' is a rarer synonym derived from the Greek root 'galakt-' for milk.
Not directly. It measures density, which correlates with overall composition. A separate device called a 'butyrometer' is designed to measure fat content specifically.
