Control the Fog in the Palm of your Hand to Find Drafts and Air Leaks with the Professional Smoke Pencil Smoke Stick.
This is the tool Professional Energy Raters and Contractors use to identify drafts and air leaks in a home. This non-toxic smoke stick generates a small trail or large puff of smoke to help you identify drafts. Pull the trigger near the area where you suspect a draft and see how the smoke moves to show air current or leakage.
Find the leak even in dark spaces! The light on the top of the Smoke Pencil One illuminates the area you are testing for easy air movement detection.
A 3oz bottle of non-toxic smoke fluid made of sweet-smelling water and glycerin (similar to fog machine fluid) is also included with the Smoke Pencil One and features a special filling tube for easy setup.
