Mercury barometers have been around since the mid 1600's.. They were
originally produced for scientific experiments and for surveyors. It was
determined long ago that the mercury would rise and fall in the tube at
different elevations. Barometers went up in balloons and were carried up
mountains to obtain elavations. Barometers could also be taken down into mine
shafts to determine depths. It was not until later that it was discovered that
the variations in the height of the mercury preceeded weather changes. This is
the primary function of the barometer as we know and use it today.
At Medford Clock Shop we specialize in the restoration of these fine
instruments. Mercury barometer tubes which have broken, or have been
contaminated with dirt or air, can be replaced, or sometimes refurbished, to
return the instrument to a functional piece. All phases of the restoration are
performed on site. We do not send the instruments out to different shops. All
tubes are also made on site for a perfect fit.
