Powder smoke wind and air detection

Powder smoke wind and air detection. Regin Powder Puffer
Smoke powder is an inexpensive, non-toxic alternative to other heat detectors. The easy-to-use bottle generates approximately 1500 puffs of "smoke".
The powder helps to visually track air balance, wind direction and air movement.
Contains a very fine silica powder (particle size 0.007 micron) which forms powder smoke when particles are released into the air.
Unlike similar products sold elsewhere, the Powder Puffer's shelf life is not affected after the bottle is first opened.
