Manometer Demonstration 300mm

Description

The demonstration Manometer is designed to take water into a ‘U’ tube. It is 100x560mm WxH and fitted with a ring for hanging on a wall. The large 12mmD clear PVC hose is formed into a ‘U’ tube with a 400mmL scale mounted between the vertical legs. The ends of the PVC tubing protrudes from the top of the instrument so other tubes can be attached for gently blowing etc. Can be used for measuring very small pressures (perhaps the pressure of natural gas) and demonstration of how such low pressures are measured in mm of water height. NOTE: The water manometer is the normal gas plumber’s method of measuring household gas pressure.
