Lab Expo NBS Smoke Chambers quantify the optical density and smoke produced by burning materials. They are made of stainless steel and have finishes that resist corrosion. They have full-size doors with viewing glass and heated room walls. They consist of both horizontal and vertical arrangements. These employ conical heaters for sample exposure. They have PMT module-based photometric optical systems installed. These include pilot burners, vent assemblies, and software-and push-button-controlled systems. They offer accurate calibration through precise furnace control. These versions contain computers, software, and DAQ gear. Our NBS Smoke Chambers have individual control modules with digital displays and retrofit possibilities.
FAQ for NBS smoke chamber
1: What is a NBS Smoke Chamber?
A NBS Smoke Chamber is a laboratory apparatus used to measure the optical density of smoke emitted by materials during controlled combustion or pyrolysis.
2: Why are NBS Smoke Chambers made of stainless steel?
Stainless steel provides high structural integrity, resistance to heat, and long-term durability essential qualities for equipment exposed to high temperatures, combustion by-products, and potentially corrosive testing conditions.
3: What is the purpose of having full-size doors with viewing glass in smoke chamber?
Full-size doors with tempered or fire-resistant viewing glass allow operators to safely observe the material behavior and smoke development during tests without interrupting the sealed environment or being exposed to hazardous emissions.
4: What is the function of a conical heater in a NBS Smoke Chamber?
A conical heater is used to expose the test sample to controlled radiant heat to simulate real fire conditions. It initiates thermal decomposition or combustion to study smoke generation and optical density.
5: Why is precise furnace control important in NBS Smoke Chamber?
Precise furnace control ensures that consistent and accurate heat levels are applied to test samples. This is critical for achieving repeatable smoke density measurements and complying with fire testing standards.
