Introduction:

Smoke Box (Smoke Density Chamber) measures optical density of smoke generated from test sample when test sample of a certain thickness is exposed to the heat source(2.5W/c㎡, *5㎾/㎡using by ASTM E **2 furnace) or fire in a chamber.

Smoke Density Tester 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 *0 ㎾/㎡ to *0㎾/㎡ or *0kW/㎡ according to different requirements.

In the test of NES **1, there are non-flaming test and flaming test in test conditions different from ASTM E **2. This test method is increasingly used in interior material of rolling stock, low power incombustible cable and interior film, etc.

Standard

• ASTM E **2: Standard Test Method for Specific Optical Density of Smoke Generated by Solid Materials

• BSI ***1: British Standard Method for Measurement, in the laboratory, of the specific optical density of smoke generated by materials

• ISO *****2: Plastics-Smoke generation -Part 2: Determination of optical density by a single-chamber test

• NES **1: Determination of the Smoke Index of Products of combustion from Small Specimens of Material 



Features:

• Integrated body and *9 analysis rack (Saving space) 

• *7 touch screen panel type PC for the whole control and automatic testing 

• Air cylinder type movement to load a sample or automatically open the up/down vent(highly resistant to pollution from the test) 

• Coating of the test chamber convenient in cleaning and resistant to chemicals   

• Lock designed to close the chamber door at a time 

• Indication of transmission rate and smoke density with improved accuracy   

• Chamber preheat system to facilitate test with more accuracy   

• Safety blow-out panel system to protect user when pressure is sharply increased during test 

• Port, heated filter, and heated line to measure toxic gases 

• Manometer gauge with increased accuracy by using the MFC(Mass Flow Controller) and DPT(Differential Pressure Transducer) enabling auto leakage test 

• Portable water cooling system without the need for waterworks and plumbing when using the Heat Fluxmeter (for ISO ***9) 

• Load cell with increased accuracy to measure mass loss rate in ISO ***9 test 

• SB ***5 DAQ(Data Acquisition) Program to control the use of touch screen panel PC
