Smoke Pen


The Bjornax reusable Smoke Emitter Pen is the perfect tool to dispense just the right amount of test smoke, when and where it is needed. A patented smoke-emitting wick is inserted into the clutch pencil and ignited. You can adjust the wick to provide a continuous stream of a light gray to white smoke. The Smoke Pen can be easily extinguished by simply replacing the protective cover. Wick diameter is 5.6mm and will burn for approximately 30 minutes each.

This cool burning, non-toxic emitter is ideal for air balancing, verifying ventilation, testing smoke alarms, test for negative or positive air pressure.
