HTB-036 NBS Smoke Density Chamber for Standard ASTM E662

Application
NBS smoke density chamber measures the optical density of smoke when a certain thick specimen is exposed to a heat source of 25KW/50KW/. It is widely employed in assessing performance of vehicle interior and noncombustible cable.

Features:
1. equipped with USA Medtherm Heat Flux meter, portable water cooling system for longer life of heat flux meter without running water supply.
2. Weighing sensor enables accuracy of mass loss rate.
3. MFC control gas flux accurately.
4. Automatically open ventilation up and down with cyclinder, evacuate the exhaust more efficiently.
5. Teflon coated inner chamber, easy to clean and corrosion resistant.
6. digital display of smoke optical transmittance and density.
7. Pre-heated apparatus made of U type heating element for quick startup and accurate data acquiring.
8. blowout panel system ensure safety, when the chamber pressure goes up very quickly during test.
9. integrated design with 19" PC of Lab view software.

Standards:
ASTM E 662: test method of specific optical density of smoke of solid material.
BSI 6401: UK Standard of measuring specific optical density of smoke of material.
ISO 5659-2: smoke generation from plastic, determination of optical density by a single chamber test.
NES 711: Measure the smoke density of a small specimen burning.
