Smoke Pen Test Kit

Vodex

£49

This Smoke Pen provides a continuous stream of dense, non-toxic white smoke perfect for leak-tests and air-flow studies. The Smoke Pen works like a mechanical pencil-simply adjust the patented smoke-emitting wick to provide 10mm of exposed length, then light the wick with a match or lighter. Provides a continuous trail of non-toxic white smoke until extinguished by replacing the protective cover. The unused portion of the wick stores safely in the barrel of the pen. The reusable Smoke Pen comes with one wick, providing a total of 30 mins of continuous smoke or about 60 individual 30-second tes

Buy from VODEX LIMITEDVODEX LIMITED is a UK retailer, not the maker. Price seen 2026-09-26. Not an affiliate link, we earn nothing from it.

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as VODEX LIMITED, number 04812548. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
