Smoke Candles, Pellets & Matches

Smoke Signal generates smoke by chemical reaction eliminating costly equipment and time to pinpoint leaks.
Smoke tests will effectively and inexpensively reveal leaks in heating and air conditioning duct work, furnaces, fire
boxes, exhaust fans and smoke detectors. Smoke Signal is also excellent for observing air flow patterns, evaluating
exhaust systems and testing smoke detectors. Smoke Signal items contain no explosive materials.
