Smoke Pencil Draught Detector


SKU: SmokePencilProKit Category:


It’s pretty obvious if you’ve got a draughty chimney: put your hand up your chimney and you will feel a strong pull of air. But what about other draughts? How do you know if you’ve got draughts coming from doors, windows, loft hatches, behind beams,  around pipes and all the other usual suspects? You could walk about trying to sniff them out or you could try out this nifty gadget. It has a heating element that heats a small amout of glycerine-based liquid that emits a sweet smelling “smoke”. This is controlable so you can let out a small steady stream to pinpoint a draught or puff out clouds of it to start narrowing down the search.
