Construction Materials Smoke Density Tester , Smoke Density Apparatus
This instrument has been established for many years and is used widely in all industrial sectors for the determination of smoke generated by solid materials and assemblies mounted in the vertical position within a closed chamber.
This widely-used test instrument measures the specific optical density of smoke generated by materials when an essentially flat specimen, up to 25 mm thick, is exposed vertically to a radiant heat source of 25 kW/m2, in a closed chamber, with or without the use of a pilot flame.
