The Drager Flow Check is the ideal tool for making invisible air movements to become visible. The plume of non-toxic, non-reactive smoke generated by the Flow Check allows one to actually see the direction, dispersion, and relative speed of the air currents in an area. Knowing how the air is moving way, you are able to more accurately take measurements in the environment knowing the air movements. This smoke can also be used to detect air leaks around doorways or other fixtures.
The Drager FlowCheck consists of:
- an instrument for the production of the clouds
- an ampoule containing smoke generating fluid.
The ampoule contains a fluid that is a special mixture of alcohol's developed at Drager. A small heating element in the head of the instrument heats the fluid which condenses on contact with the ambient air. The temperature of the heating element and the quantity of the fluid is electrically balanced.
The Drager Flow Check incorporates ergonomic form, low weight, and optimal operation into the instrument design. The unit will generate clouds in any orientation. Small, single clouds can be generated with a short press of a button. lf a continuous production of clouds is desired, the button can be held or locked in the "on" position. The fluid ampoule is located in a compartment in the handle of the instrument and can be inserted effortlessly into position. The amount of fluid contained in the ampoule is enough to generate a continuous cloud for a period of approximately three minutes. Power is supplied by a battery located in the handle of the instrument and can be charged while inside the instrument or separately.
