Large model of aneroid barometer.
2B35.40 • C+30+45
Large model of aneroid barometer. A flat metal box, partially evacuated and with flexible sides, is attached at 'A' to a lever. As atmospheric pressure increases, the box is compressed and the pointer goes to the left. As atmospheric pressure decreases, the box expands and the pointer goes to the right. FLUID STATICS.
