Computerized NBS Smoke Density Chamber Standard Size With
Transparent Tempered Glass Door
Smoke density tester for building materials, used to measure the
smoke density of building materials under the conditions of
combustion or decomposition test conditions, through the loss of
luminous flux in the test chamber for smoke density test, can be
observed during the test flame and smoke phenomenon.
ASTM D2843 smoke density test
GB / T 8627 Smoke density test
Firstly, the appearance of advanced industrial design and control;
fully consider the test of human and environmental impact.
1, Steel box, durable;
2, Transparent tempered glass door for observation and testing;
3, Stainless steel sample folder;
4, With the main burner and auxiliary burner.
5, Needle valve to adjust the gas flow, pressure regulating valve
to adjust the gas pressure.
6, The exhaust volume of 1700L / min
7, 300 mm optical path.
Secondly, the experimental data accurate
Using the focus of the light source system and the use of imported
silicon optical amplifier optical receiver system; data stable
Thirdly, PC computer + Labview special software control:
1, Automatic ignition;
2, Can be entered in the operating software, the flame appears
time, flame out time, sample burn time, mark fuzzy time. Accuracy
3, Data acquisition, calculation, save, print output
Real-time data and smoke density curve display / historical curve
and data display and query.
Firstly, the combustion box:
