Jolly Bulb with Gauge
A glass Jolly bulb, 60 mm in diameter, connected directly to a Bourdon gauge calibrated in kg/cm² and psi. It is used to investigate a gas at constant volume: dipping the bulb in warm or cold water makes the trapped air expand or contract, which shows up as a change in pressure on the gauge.
