## Description

Control the Fog in the Palm of your Hand to Find Drafts and Air Leaks with the Professional Smoke Pencil ONE Smoke Stick.The Smoke Pencil 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. Simply pull the trigger on the Smoke Pencil near the area that 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 illuminates the area you are testing for easy air movement detection. A 3oz bottle of non-toxic smoke fluid made of sweet smelling water, glycol, and glycerin (similar to toy train smoke) is also included with the Smoke Pencil and features a special filling tube for easy setup.SMOKE PENCIL FEATURES: Includes handheld 3â x 5â x 2â inch Smoke Pencil draft and air leak detector with 3 oz non-toxic smoke fluid fog juice that lasts about 12-15 hours. You control the amount of smoke this Smoke Pencil generates by pulsing the finger trigger. The fog comes out of the top chimney to reveal any drafts or leaks in your home, automobile, or business. It does not use the dangerous and caustic acid or incineration based smoke that other smoke sticks often produce. Only consumes batteries and fluid when the trigger is pulled. Robust body frame that resists drops and damage. Used by energy raters, HVAC technicians, auto mechanics, photographers, window salesman, airplane technicians, hospital maintenance, and contractors. Locking trigger for easier toolbox storage. 6 - AA batteries required (not included). 30-Day Money-Back Guarantee. Order your Smoke Pencil Air Leak Detection Hazer today for a safer and simpler way to detect drafts and air leaks.

Review: This smoke pen has been an incredibly useful tool for understanding air movement in my home, particularly for diagnosing radon mitigation effectiveness. It produces a steady, visible stream of smoke that makes it easy to track airflow patterns around vents, doors, and basement areas. The build quality is solid, and after months of use, it still performs just as well as when I first got it. It’s compact, easy to handle, and doesn’t create any mess or strong odors. Unlike DIY alternatives, this pen provides a controlled and consistent smoke output, making it much more reliable for precise testing. For the price, it’s an excellent value. Whether you're troubleshooting radon mitigation, HVAC efficiency, or general ventilation issues, this smoke pen is a must-have tool. Highly recommended for its durability, ease of use, and affordability!

## Questions & Answers

**Q: Do you have a safety data sheet (sds) for the fluid? i need one for work requirements.**
A: Yes, we do have an SDS on the fluid. I cant attach a PDF here on this Q&A tool, but if you reach me by message I can send it to you.

**Q: I want to test the air flow in a computer case.  Does the smoke leave any residue that would damage electronics?**
A: When glycerin is used the smoke created is not harmful to electronics in small amounts, but it does contain water molecules that can harm electronics if overexposed. There are smoke products that are used in the testing of smoke detectors that are extremely low or no residue as required by NFPA standards. Just google for smoke detector test smoke.
