Visually and effectively demonstrate the relationship between temperature and pressure with this new Joly bulb.
The digital Joly 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 60mm bulb in water at different temperatures the relationship between temperature and pressure may be demonstrated and the digital readout allows a quantitative investigation to be carried out if required.
