Fortin Barometer with Mercury

Fortin Barometer with Mercury is a precision instrument used to measure atmospheric pressure with high accuracy. Named after its inventor, Jean Nicolas Fortin, this barometer features a mercury column enclosed in a glass tube, mounted vertically with a cistern at the base. A screw-adjusted ivory point is used to align the mercury level at the reference point, ensuring consistent and accurate readings. The device includes a vernier scale for fine measurements and is enclosed in a protective casing for safe handling. Commonly used in meteorological studies, physics laboratories, and calibration settings, the Fortin Barometer is essential for barometric pressure determination and experimental demonstrations.
