Product Overview
This demonstration barometer uses a well-made aneroid movement mounted inside a plastic dome with all parts in clear view so that its operation can be studied. The dial is 150 mm in diameter and is calibrated in both kPa and mmHg so that it can be used as the common aneroid barometer in addition to being an ideal demonstration instrument. The plastic dome can be removed for close study or adjustment of the mechanism.
In addition to indicating true atmospheric pressure, the pressure within the dome can be arbitrarily increased by means of a rubber bulb to show how the mechanism reacts to pressure changes. The bulb and connecting silicone rubber tubing are included. The bulb can be removed, and suction applied to the outlet to demonstrate reduced pressure.
