About This Product
Connecting a gas supply to the side arm through rubber tubing pushes the liquid down one limb and up the other, and the difference in levels read off the metric scale shows the pressure. Coloured water makes the columns easier to see from the back of the room. Disturbing the liquid and letting it settle also demonstrates how columns of liquid oscillate.
