Product Description

Introduction:
The Smoke Chamber has proved to be one of the most versatile fire testing instruments since its inception in the ***0s. It is the most widely accepted apparatus for the measurement of smoke from burning materials and measures specific optical density under flaming and non-flaming conditions. It is also used for the extraction of toxic gas.
This testing equipment is satisfied with standards (ASTM E **2, BS***1, ISO ***9, NES **1, NEPA **8, etc).
Using ISO ***9 conical radiant heat furnace, We can change the heating condition from *0KW/㎡to 5KW/㎡by user.
In the test of NES **1, there are non-flaming test and flaming test in test conditions different from ASTM E **2.

  Feature:

• The inner dimensions of the chamber is **4mm±3mm long, **4mm±3mm high and **0mm±3mm deep.
• The inner surface is consist of Teflon coating, which is resistant to chemical attack and corrosion and easily cleaned.
• Test chamber with full width opening door, allowing easy access for sample loading and chamber cleaning.
• Provided with a hinged front-mounted door with an observation window and a removed opaque door cover to the window to prevent light entering into the chamber.
• Chamber walls are pre-heated for easier start-up and convenient equipment operation.
• Safety blow-out panel, easily replaceable, allows for safe operation of test method.
• Two optical windows, each with a diameter of *5mm, mounted in the top and bottom of cabinet.
• The light measuring system is consist of Incandescent lamp and photomultiplier tube.
• Provided with range-extension filter in the light path, adjusting the accuracy of instrument under the any scale.
• Conical Heater - is wound in the form of a truncated cone, rated ***0 W at **0 V with a heat output of *0 kW/m2.
• Auto Split Shutter automatically opened to transmit radiation to the sample, Spark Igniter to ignite the sample.
• Heat Flux Meter - for setting the irradiance level at the surface of the specimens, the range from ****0KW/m2.
• Furnace Heater, rated **0W at **0 V with a heat output of *5 kW/m2.
• The movement of sample is controlled by air cylinder automatically.
• Air Cooled calorimeter for setting the irradiance level at the surface of the specimens.
• Provided with no pilot flame and pilot flame modes. Digital display flow rate of air and propane.
• Gas measurement ports are provided, for optional measurements of toxic gases.
• *9 analysis rack, *5 touch screen panel type PC for the whole control and automatic testing.
• DAQ(Data Acquisition) Program controllable with the touch screen panel PC.
• Testing results: Light transmission、Optical density、Mass optical density（MOD）、Mass loss rate、the Clear-beam correction factor etc
