S210: 20 Pack of Splintax 10-20 Second, 20 Cubic Feet White/Grey non-toxic smoke
emitters. These smoke
matches provide a quick and inexpensive method of
generating a small burst of smoke. A great product for testing low pressure duct-work systems and also for air balancing. The smoke
emitted does not contain oil nor zinc and will not leave any residue. It is
non-toxic and has the same density as air, so that it is possible to observe
true air movements without the complicating factor of having to allow for the
natural rise or fall of the smoke. The particle size is 0.3 to 2.5 microns making it
ideal to check HEPA filters.
Warning: Poisonous to swallow. To be kept away from children
& animals. Do
not use smoke emitters near flammable materials, gas etc.
