                NBS Smoke Density Chamber

                share:

                BRAND:Motis MODEL:SDB

                INTRODUCTION

                The Smoke Chamber has proved to be one of the most versatile fire testing instruments since its inception in the 1980s. 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 equipment is satisfied with standards (ASTM E 662, BS6401, ISO 5659, NES 711, NEPA 258, etc).

                • Using ISO 5659 conical radiant heat furnace, We can change the heating condition from 10KW/㎡to 5KW/㎡by user.

                • In the test of NES 711, there are non-flaming test and flaming test in test conditions different from ASTM E 662.

                FEATURE

                • The inner dimensions of the chamber is 914mm±3mm long, 914mm±3mm high and 610mm±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 75mm, 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 2600 W at 230 V with a heat output of 50 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 0-100KW/m2.

                • Furnace Heater, rated 550W at 110 V with a heat output of 25 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.

                • 19 analysis rack, 15 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.
