FY818-II NBS Smoke Density Chamber is used for measuring smoke density which produced from the exposed surface of specimen,such as plastic, rubber, textile coverings, wood, etc. The smoke optical density is measured continuously by an optical system according to Beer-lambertlaw. This chamber can also be matched with other instrument, such as FTIR,HPLC, ion chromatograph, gas detector, to analyze smoke toxicity.
