DESCRIPTION :-

• Verticaly mounted Omm diameter, with stop cock

• The Fortin Barometer, the level of mercury in the glass at the bottom of the barometer cistern is adjusted to a scale zero, known as the fiducial point, each time a reading is to be taken.

• The level of mercury in the column is then read against the scale, using a vernier adjustment for extra accuracy. 

• Air is evacuated from the top of the tube of mercury and the lower end is fixed in the cistern containing the reservoir of mercury.

• The Fortin barometer is simple to use as it has a clear easy- to-read linear scale.

• These barometers can be mounted on a wall or suitable pillar.

• Fortin barometers can be moved without risk of damage but always be carried flat or upside down.

• If a Fortin barometer is to be moved after installation, the following procedure followed: turn the adjustment screw until the mercury fills the reservoir and the mercury in The column is about 25 mm from the top of the scale.

• Remove the barometer from the wall, incline or tilt gently and then place in a flat position. Finally, adjust the screw further until a small air gap is left in the reservoir.

• The re-hang the instrument, reverse this procedure.
