Dräger Flow Check
For the optimal setting of heating, ventilation and air conditioning systems, air flows have to be located accurately and precisely. Using the Flow Check air flow indicator even the slightest air movement is made visible, so the origin, direction and relative speed can easily be detected. The device produces a cloud of smoke, that floats freely and easily, because it has the same density as ambient air.
The Dräger 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.
The ergonomically designed, hand-held instrument is light weight and offers a single button for ease of operation. Pressing the button for a few seconds creates short burts of smoke or continuous smoke by pressing and locking the button.
