Barometer Fortin's, Aluminium

Fortin's barometer with an aluminum frame is a precision instrument designed to measure atmospheric pressure. It features a mercury column enclosed in a glass tube, mounted on a lightweight yet durable aluminum frame. The barometer includes a scale to read the mercury height and an adjustable cistern to set the mercury level for calibration. The use of aluminum makes the instrument more corrosion-resistant and easier to handle compared to traditional brass models, while maintaining accuracy and reliability in pressure measurement.
