Foam Verification Kit - 14028-4

Comprising an air pump, a test selector valve, two air control regulators, glassware, digital manometer and a flowmeter, all mounted on a chassis with the necessary manifolds and interconnecting tubes.

For pore diameter verification the test selector valve directs air via the 'porosity' air control regulator to the diffuser / stone, which is immersed in water in a 250 ml glass measuring cylinder. The digital manometer reads the air pressure required for a bubble to appear at the diffuser / stone.

During permeability verification the test selector valve directs air via the 'permeability' air control valve to the diffuser / stone which is in a 250 ml Buchner flask, the outlet of which is connected to the flowmeter. The flowmeter shows the airflow when the digital manometer shows a specified air pressure upstream of the diffuser / stone.Supplied with;
