About This Product

Squeezing the bulb increases the pressure on the aneroid capsule and the pointer swings one way; releasing it lets the reading fall back. This turns an instrument that normally changes over hours into a live demonstration of how an aneroid barometer responds, and a starting point for lessons on air pressure and pressure units.

Frequently Asked Questions

How is the pressure changed during a demonstration?

A rubber compression bulb with a tubing connection varies the air pressure, showing the effect of increasing or decreasing pressure on the reading.
