Common Mistakes When Using “fortin barometer”
- Mispronouncing 'Fortin' as /ˈfɔːr.tɪn/ (like 'fort' + 'in') instead of the French-derived /ˈfɔː.tæ̃/ or /ˈfɔr.tn̩/.
- Using it as a generic term for any barometer.
- Incorrect capitalisation (e.g., 'fortin Barometer').
FAQ
Frequently Asked Questions
No. All Fortin barometers are mercury barometers, but not all mercury barometers are of the Fortin type. The Fortin design specifically has an adjustable leather bag (cistern) at the base.
It is named after Jean-Nicolas Fortin (1750–1831), a French instrument maker who perfected this design to improve accuracy and ease of use.
In settings requiring high-precision pressure measurement: physics and meteorology laboratories, calibration facilities, and as a reference standard in observatories.
Yes, but primarily as a primary standard for calibration. For everyday use, digital and aneroid barometers are more common due to safety concerns with mercury and convenience.
A precise type of mercury barometer, consisting of a glass tube filled with mercury, whose base is sealed by a flexible leather bag (the Fortin cistern) that can be adjusted with a screw to set the mercury level to a fixed point before taking a reading.
Fortin barometer is usually technical/scientific in register.
Fortin barometer: in British English it is pronounced /ˈfɔː.tæ̃ ˈbæˌrɒm.ɪ.tə/, and in American English it is pronounced /ˈfɔr.tn̩ ˌbəˈrɑːm.ə.t̬ɚ/. Tap the audio buttons above to hear it.
