Computerized NBS Smoke Density Chamber Standard Size With Transparent Tempered Glass Door
Descriptions:
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.
Standard:
ASTM D2843 smoke density test
GB / T 8627 Smoke density test
Features:
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;
