These smoke pencils are battery operated smoke sticks. A very small internal heating element heats the Glycerine, Glycol & Water solution to produce a fine steam that looks like smoke. The smoke is non-toxic, smells faintly sugary and is of a good consistency for draught testing.

The smoke density and duration are easily controlled by a progressive trigger. Being produced electrically, smoke is always available on demand. There is also a built-in LED light that helps to illuminate the area you are testing. Batteries last a long time, 1400 mAh or better NiMH rechargeable batteries are recommended.

Transportation Note: Other types of smoke sticks and smoke puffers have very dangerous chemicals or inflammables in them. Most of these other smoke sticks can’t even be taken on to a plane or sent via Air Package Carrier or post because of these materials. This Smoke Pencil is different since it operates on a harmless glycol, glycerine and water vapour. Also the smoke fluid comes in a small 3 oz (89 ml) bottle that is allowable by the CAA.
