tasimeter
Very LowTechnical/Historical
Definition
Meaning
A sensitive instrument for detecting or measuring minute changes in pressure or temperature, typically through changes in electrical resistance.
A specific type of extremely sensitive hygrometer (humidity detector) invented by Thomas Edison. Historically, it was used in scientific experiments to measure minute atmospheric or thermal variations.
Linguistics
Semantic Notes
This is an obsolete, highly specialized term from 19th-century scientific instrumentation. It is rarely encountered outside historical texts discussing the history of technology or Edison's inventions.
Dialectal Variation
British vs American Usage
Differences
No significant differences in usage. The term is equally archaic and technical in both varieties.
Connotations
Connotes historical science, precision instrumentation, and Edison's work.
Frequency
Extremely rare in contemporary usage in both regions. Might appear marginally more in American texts due to Edison's nationality.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'тахиметр' (tachymeter, a speed-measuring device).
- The 'meter' part is from Greek 'metron' (measure), not related to the SI unit 'metre'.
Common Mistakes
- Misspelling as 'tacimeter' or 'tassimeter'.
- Using it as a general term for any modern sensor.

FAQ
Frequently Asked Questions
No, the specific tasimeter design is obsolete. Its function is performed by far more advanced and sensitive modern electronic sensors and hygrometers.
It derives from the Greek 'tasis', meaning 'stretching' or 'tension', referring to the instrument's operation based on the physical stretching of materials (like carbon) in response to stimuli.
The American inventor Thomas Alva Edison invented and patented the carbon tasimeter in 1878.
You would only encounter it in detailed historical accounts of scientific instrumentation, biographies of Thomas Edison, or academic papers on the history of technology.
