Smoke Generating Candles


Light the wick to produce a short burst of smoke to detect airflow and leaks in HVAC systems.
Use candles with two wicks to extend burning time. Link the wicks with included cable ties. When the first wick burns down, the second lights. Each wick you link adds 3 minutes of burning time.
Contaminant-Free Smoke Generating Pellets

Detect airflow and leaks in places with sensitive electronics, such as server rooms. The smoke from these pellets contains only trace amounts of chloride, so it won’t cause electronics to corrode. Ignite them to create a short burst of smoke.
Smoke Powder


Release a burst of floating powder to detect airflow and leaks in HVAC systems, no flame or ignition source required.
Squeeze-bulb powder creates a denser cloud than squeeze-bottle powder, so you can more clearly see air movement. It requires a rubber squeeze bulb (sold separately) to operate.
