Using refillable wicks, the device works like a mechanical pencil; where a wick can be inserted into the pen, leaving a 10mm trace that can subsequently be ignited by either a lighter or match. The patented design of the wick ensures a continuous and consistent smoke trail, helping simplify ASD system smoke testing. Once smoke testing has been completed, smoke can be quickly extinguished by replacing the smoke pen lid, leaving the wick ready for reuse at a later date. The Smoke Pen comes with 6 replacement wicks, and a separate refill pack is available as a spare part.
