Smoke Candles from Superior Signal produce smoke by chemical reaction.  Use them to conduct smoke tests

.

Choose from three burn times and smoke volumes to meet your needs.

Leak Detection:  Superior Smoke is highly visible, blending readily with air and gases.  While the burning candle is hot, the resulting smoke is cool and does not support combustion.  Invisible leaks become readily detectable when Superior Smoke is added.  To detect leaks in small- or medium- sized enclosures--such as furnaces, tanks, piping systems and ductwork--use enough smoke to fill a volume at least 2-3 times greater than that being tested.  

Air-Flow Studies:  Superior Smoke simplifies the observation of flow patterns in all types of wind tunnels, air-moving equipment, and natural airflow, indoors or out.  Generally, 1 part smoke to two parts air (volume:volume) provides readily viewable results.  Balance HVAC system by observing the discharge of smoke from ducts and supply grilles.  

Photography:  Superior Smoke photographs from white to dark gray, depending on smoke density and lighting.  Dramatic color effects can be achieved by directing colored lights through thin concentrations of the smoke.

Caution:  The smoke emitted from Superior Smoke Candles is non-toxic, but can irritate breathing passages when respiratory protection is not used.  Click here for Smoke Candles MSDS
