Air Flow Tester, Set

• Product specific notes: set

In many fields, such as mining or industry, it is very important to detect even the smallest air flows, in order to quickly and reliably evaluate the possible diffusion of dangerous substances. With the air flow test tubes, the source, direction and speed of the air flow are visible immediately.

The set contains 10 flow test tubes, a handy blower ball and rubber caps, all securely stored in a sturdy plastic box with a built-in tube-breaking device. The tubes are impregnated with fuming sulphuric acid, which produces white smoke when air is blown through them. This smoke is carried by air currents, making it possible to visualise the finest movements of the air.
