Principle of Operation:
The MCS002 Laboratory Air-Barometer or Sympiesometer depends for its operation on the precise measurement of a fixed volume of air retained in a vessel above a column of fluid supported by the atmospheric pressure. As the latter varies, the captive gas is compressed or rarified and the barometric fluid level in the column varies accordingly. At constant temperature, this height is very nearly proportional to the atmospheric pressure, there being a small further term varying as the square of the pressure.

Temperature, however has a large effect, but which can be allowed for precisely by the incorporation of sliding scale which is adjusted to the thermometer thread before a reading is taken. In the MCS002, this sliding scale runs in a vertical track alongside the thermometer and the barometric column. It is retained in the track magnetically and can be moved to align an index with the thermometer thread, after which the atmospheric pressure can be read directly from the position of the barometric fluid against the pressure scale.
