An apparatus to quickly verify the maximum pore diameter and permeability of Mott diffusers (Cylindrical Metal Diffuser and Tube (14023-0)) and Norton stones (Spherical Diffuser and Tube (14021-0)).

For use wth the SetaFoam Dual Twin Foam Test Baths (14020-8).

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.

Features

• Verifies maximum pore diameter and permeability of diffusers
• Suitable for Mott Diffusers and Norton Stones
