Smoke testers come in a wide range of sizes and weights that each emit a different amount of smoke. Sizes and amount of smoke emitted may vary depending on manufacturer.
3gm smoke emitter pellets have a burn time of between 30-40 seconds and emit 7-8 cubic metres of smoke. These small pellets would be ideal for testing the draw of a chimney or small domestic tasks like testing for air leaks and draughts around fixtures and window seals.
5gm smoke emitter pellets have a burn time of between 30-45 seconds and emit 8-12 cubic meters of smoke. Pellets of this size are ideal for testing the draw of a larger chimney or for checking your ventilation for air flow and draw.
8gm smoke emitter pellets have a burn time of between 45-60 seconds and emit 15 cubic metres of smoke. These size pellets are ideal for testing your chimney for leaks and defects.
9gm smoke emitter pellets have a burn time of between 60-65 seconds and emit 18 cubic metres of smoke. These pellets are also used for testing chimneys for leaks and defects. Several of them may be used to test larger areas like sewers and drains.
13gm smoke emitter pellets have a burn time of between 60-65 seconds and emit 24 cubic metres of smoke. These 13gm smoke pellets can be used to test large chimneys for leaks, test for draw or several of them may be used to test underground sewers and drains.
Smoke matches, when lit, emit a low-toxic, white smoke and have a burn time of 20 seconds. Smoke matches are ideal for testing your smoke alarms, finding draughts and air leaks around doors and window seals.
What does “burn time” mean?
The burn time of a smoke tester is the length of time that it produces smoke before naturally extinguishing itself.
