Smoke Pen Kit with 3 Smoke Sticks - Precise Leak & Airflow Tests

In this review the Arctic Hayes Smoke Pen kit is examined for tradespeople and building inspectors who need a compact, controllable smoke source for identifying drafts, testing extraction arms and confirming gas or CO spillage paths. The bottom line: this is a straightforward diagnostic tool that produces a pencil-thin stream of white smoke for up to three hours total, making it useful for slight air-movement checks and mandatory post-fit boiler/case sill spillage tests where visibility and controllability matter.

Key Features

• Innovative smoke testing design: The pencil-thin smoke pattern creates a focused plume that makes small drafts and leakage paths easier to spot than bulk smoke sources.
• Three smoke sticks included: The kit supplies three refills, giving around 30 minutes of smoke per stick and roughly three hours of controllable use overall for extended testing sessions.
• Safe and non-hazardous output: The white smoke is described as non-corrosive and non-hazardous, so it can be used around alarm systems and in ventilation ducts with minimal material risk.
• Simple push-button operation: The pen holder opens like a mechanical pencil to insert sticks, and a cap lets the user extinguish a stick quickly to control smoke production.
• Applications-focused: The product is intended for leak testing, airflow studies, ASD testing, extraction arm flow checks, and compulsory CO spillage checks after boiler installation.

Who It's For

The Smoke Pen suits HVAC technicians, fire alarm engineers, gas fitters and building inspectors who need a portable, precise smoke source to visualise slight air movement, duct leaks, or verify CO spillage around boiler and case sills after fitting or re-fitting. Its pencil-thin output is especially helpful for pinpointing small leaks that would be missed by larger smoke generators.

It is less suitable for users who require heavy, long-duration theatrical smoke or large-volume duct filling; those tasks need larger generators. Also, if absolute value-per-stick is the main concern, some customers see mixed value compared to simpler methods.

Pros & Cons

Pros

• Visible, focused smoke output makes diagnostic work and draft testing clearer and faster.
• Compact pen form factor and simple mechanism make it easy to carry and operate on site.
• Includes three smoke sticks so a typical inspection kit is ready out of the box.

Cons

• Some customers report mixed feelings on value for money compared with alternatives.
• The smoke duration per stick is finite (about 30 minutes), so larger jobs require extra refills.

Specifications

Our Verdict

The Smoke Pen kit is a practical, purpose-built diagnostic aid for professionals who need a precise, controllable smoke source for leak and airflow checks and mandatory boiler/case sill spillage testing. It delivers clear smoke output and convenient portability, though users should account for refill needs on larger jobs; for targeted inspections it offers good utility and sensible performance.

Frequently Asked Questions

How long does each smoke stick last?
Each stick produces around 30 minutes of smoke, and the kit includes three sticks for roughly three hours of total run time.

Is the smoke harmful or corrosive?
The smoke is described as continuous and non-corrosive and is intended to be non-hazardous for diagnostic testing applications.

Can the smoke be extinguished quickly on site?
Yes, replacing the cap on the pen will extinguish the stick so the operator can control smoke output during tests.
