We make both aneroid
and mercury barometers. We use high quality movements in our reproduction aneroid
barometers.
Mercury barometers contain a glass tube about a metre long
which is filled with mercury. This was the general method of
measuring air pressure until the mid 19th century when the
aneroid barometers became popular.
In order to comply with the European Union REACH Enforcement Regulations 2008 No.2852 mercury filled reproduction barometers can only sold to trade, companies or businesses and not to private individuals within the EU. Unfilled reproduction barometers can continue to be sold to private individuals. Restoration or the sale of mercury barometers over 50 years old are not subject to this ruling. For more information please contact Edmund Czajkowski & Son Ltd.
Although originally not so accurate, the aneroid barometer
could be made smaller and was more portable since it contains
a small circular metal box containing a vacuum which is linked
to a pointer. Changes in air pressure on the box allows the
pointer to record the changes in the same way that in a mercury
barometer, changes of air pressure allow the mercury level
to rise and fall.
Michael Czajkowski, the owner of the firm, is an accredited
conservator with the Institute of Conservation (ICON), a member
of the British Antique Furniture Restorers (B.A.F.R.A.) and
as such adhere to the best principle of conservation practice.
Below are some examples of our work, these are all made in
our workshop.
