NBS Smoke Chamber 71-SC100

71-SC100 NBS Smoke Chamber as proved to be one of the most versatile fire testing instruments. It is the most widely accepted apparatus for the measurement of smoke from burning materials and to measure the specific optical density under flaming and non-flaming conditions. It is also used for the extraction of toxic gas. This orientation is also used for FAA testing. The instrument as both vertical and horizontal configuration. A sample is exposed in the horizontal plane by a conical heater. In addition the smoke chamber can be utilized for toxicity measurements using our toxicity chamber option. The concept of smoke chamber incorporates all the necessary features and software needed to complete tests, as a simple, ergonomic and user friendly.
