explosimeter
Very LowTechnical / Industrial
Definition
Meaning
A device for measuring the concentration of explosive gases or vapors in the air.
A portable instrument used primarily in mining, chemical industries, and safety inspections to detect and quantify the presence of flammable atmospheres to prevent explosions.
Linguistics
Semantic Notes
The term is highly specific to industrial safety and occupational health contexts. It is a compound of 'explosi-' (from explosive) and '-meter' (measuring device). It refers to the instrument itself, not the person using it.

Examples
By CEFR Level
- The miner carried a special device for safety.
- Before entering the tank, the worker checked the air with a meter.
- Safety protocol requires the use of an explosimeter to test for flammable vapors in confined spaces.
- The readings from the newly calibrated explosimeter indicated a methane concentration well below the lower explosive limit.
Learning
Memory Aids
Mnemonic
Think: EXPLOSIve + meter (like thermometer) = EXPLOSIMETER, a meter for explosive stuff.
Conceptual Metaphor
A CANARY IN A COAL MINE (modern, technological version).

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation or creation of a similar-sounding Russicism. Use established technical translations like 'газоанализатор' or 'взрывомер' only in precise contexts.
Common Mistakes
- Confusing it with a 'smoke detector' or 'fire alarm'. Using it as a verb (e.g., 'to explosimeter').

FAQ
Frequently Asked Questions
An explosimeter is a specific type of gas detector designed to measure concentrations of flammable or explosive gases, typically displaying the reading as a percentage of the Lower Explosive Limit (LEL).
They are used by safety engineers, miners, firefighters, chemical plant operators, and anyone working in environments where explosive atmospheres may form.
Typically, no. A standard explosimeter is calibrated for flammability, not toxicity. Multi-gas detectors combine these functions.
No, it is a very low-frequency technical term unknown to the general public but standard within specific industrial safety fields.
