The Aneroid Barometer is a robust and simple to use, wall-mounting instrument for general purpose atmospheric pressure measurement. The instrument is of traditional design set on a dark wood base. The 95mm diameter dial has scales graduated in both millibars and inches of mercury, a settable pointer and an adjustment screw are also provided. It is an ideal instrument for observing weather related pressure trends.

This instrument is made to a British Meteorological Office specification and is the standard type of barometer used in synoptic and climatological weather stations throughout the world. It is also entirely suitable for use in any laboratory or workshop where accurate knowledge of the atmospheric pressure is required.

Two versions of the Aneroid Barograph
are available; the ‘Small Pattern’ and the ‘Display Pattern’. Both have an 8-day clock and are housed in elegant polished wood cases. The Display pattern has all round glass and an additional drawer to house spare charts.

The Fortin Barometer is the most widely used technique for measuring atmospheric pressure in industrial laboratories and workshops as well as in school, college and university laboratories.

Principles Of Operation
The Kew Pattern Barometer consists of a column of mercury supported within a vertical glass tube, the top of which is evacuated and sealed. The lower end of the column fits into a cistern containing mercury. The height of the mercury column supported by atmospheric pressure is measured against a graduated scale and vernier.
