This unique instrument in that classical combination of polished oak, turned brass and hand-blown glass is not only a fine exponent of traditional scientific craftsmanship but is provides an accurate measurement of atmospheric pressure at any temperature in its range.
It is simple to set up and adjust using the knurled thumbwheel and the sliding temperature scale.
Low vapour-pressure barometric fluid is provided to ensure precision and long-term stability of the instrument.
This is an instrument which you will be glad to use and proud to own.
It represents a development of the sympiesometer as an attractive wall-mounted
instrument which is simple to set up and very straightforward to read. The instrument
consists of a captive gas reservoir connected by a glass helix to a liquid reservoir.
Temperature compensation is achieved by providing a thermometer with the correct rate
mounted vertically downwards alongside the glass helix together with a sliding scale.
This scale has an index which is aligned with the end of the thermometer thread,
after which the atmospheric pressure can be read from the glass helix using the adjacent
pressure calibrations. Additional precision is achieved using a low volatility mineral
oil as the barometric fluid.
The Meteor-0ptic series of barometers are mercury-free alternatives to traditional mercurial instruments but the non-mercury based instrument has a long and distinguished history. Please see our KNOWLEDGEBASE which gives technical information on these instruments and their performance.
1) Carefully remove instrument from packing.
2). Choose a safe place for your sympiesometer, away from draughts and out of direct sunlight,
and reasonably constant in temperature. Attach the instrument securely to the wall using the wall
plate mounted at the top rear.
3) Carefully unscrew the black cap on the lower liquid reservoir and fill with the coloured mineral
oil provided.
4) Leave for three hours to reach a stable temperature.
6) Obtain a reading for the atmospheric pressure at your location in millibars.
7) Adjust the sliding scale until the red index is adjacent to the end of the thermometer thread.
11) Carefully turn the knurled thumbwheel clockwise. The liquid level will rise in the glass coil.
12) Continue rotating the thumbwheel until the liquid level reaches the
height appropriate to the current pressure indicated on the sliding scale.
1) Adjust the sliding scale until the red index is adjacent to the end of the thermometer thread.
2) Read the pressure by observing the position of the liquid level in the helix in relation
to the sliding scale.
