Air Current Measurement
Dräger Smoke Tubes have been very
popular in the HVAC and mining indus-
tries for many years. The reagent inside
the smoke tube produces a visible
aerosol plume when in contact with
atmospheric humidity. A simple squeeze
bulb pushes air through the tube to propel
the smoke into the ambient air. Even the
most gentle air currents are made visible.
Air current directions and flow rates are
very important to gas detection. The visi-
ble plume of non-toxic, non-reactive
smoke generated by the Dräger Flow-
Check allows you to actually see the
direction, dispersion, and relative speed
of the air currents in an area. Knowing
how the air is moving, you are better pre-
pared to accurately measure gases. This
smoke can also be used to detect air leaks
around doorways or other fixtures.
Dräger Flow-Check is also popular for
checking the effectiveness of ventilation
ducts, pressurized rooms, fume hoods,
vapor extractors and other air movement
equipment. These functions assist those
in the HVAC, hospital laboratory, and
manufacturing industry sectors.
