Dräger Flow Check - Air current detector

The Dräger Flow Check

The Flow Check is composed of a mist generator and an ampoule containing a smoke-producing fluid (an alcohols mixture harmless to the environment). A small heating element located in the head of the device heats the liquid which, upon entering the atmosphere, condenses into a mist. Its design combines ergonomics, low weight and ease of use.

The device is able to produce fog in any direction. Small clouds of fog are produced one by one at the push of a button. For a continuous production of fog, just to keep the pressure on the button or lock it in the “on” position. Located in a compartment in the handle of the instrument, the liquid smoke bulb is easily inserted. The amount of liquid in a bulb is enough to produce fog continuously for about three minutes. In order to be able to optimally adjust air conditioning systems, the air flow tester must be located exactly and precisely. The Flow Check air flow detector lets you see even the slightest air movement with the naked eye. Its origin, trajectory and speed can thus be easily detected in order to ensure proper functioning of air conditioning systems and chimneys.
