Air flow tester

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

Smoking sulfuric acid is located in the tubes. When the top of the tube is opened, a small rubber ball is used to pump air through the tube. This creates visible white smoke, which is carried on any existing air flows.

Flow-Check air flow indicator

With the Flow Check air flow indicator even slightest air movements are made visible to the eye so that their origin, course and speed can be easily detected. The device produces a cloud of smoke, that floats freely and easily, because it has the same density as ambient air.

Flow Check consists of one device for the smoke production and an ampoule containing smoke-generating fluid (an alcohol mixture that is harmless to the environment). A small heating element in the head of the instrument heats the fluid, which condenses on contact with the ambient air.

Easy to use
The ergonomically designed instrument is of low weight and offers an optimum ease of operation. Individual little fog clouds are generated at the touch of a button. For a continuous fog generation simply press the button constantly or lock it. Temperature of the heating element and the quantity of the ampoule fluid are electronically balanced.
