Digital Jolly Bulb

Description

SP4-0487
Visually and effectively demonstrate the relationship between temperature and pressure. The Digital Jolly Bulb is
the perfect alternative to the traditional bulb and analogue
gauge, pressures can be read directly from the built in digital display and the apparatus is sensitive enough to register an increase in pressure when the bulb is held gently
in the hand. By submerging the bulb in water at different
temperatures the relationship between temperature and
pressure may be demonstrated and the calibrated digital
readout allows a quantitative investigation to be carried out
if required.
