Smoke Density Test Machine for Building Material

INTRODUCTION

In fire, people are often smoke suffocated or unable to escape because of the invisible road, so in the prevention of fire,smoke density of the test material is essential.
This smoke density test machine conforms to the international standard ASTM D2843 specification and requirements, it can be used to measure and describe response to heat and flame under controlled laboratory conditions.It can also measure smoke producing characteristics of plastics under controlled conditions of combustion or decomposition.

FEATURE

• The test chamber is painted, beautiful, durable anti-corrosion;

•  Transparent glass doors for easy observation of the test;

•  Stainless steel sample holder and sample templates are equiped with smoke density test machine;

•  The light absorption rate: 0-100% can be measured continuously. Smoke density resolution 0.1%;

•  The smoke density measurement accuracy: ± 3%;

•  With the main burner and pilot burner.

•  The test machine is equipped with exhaust fan, exhaust the smoke aftertest; exhaust volume 1700L/min;

•  300mm optical path. 480mm height distance above the base;

• The optical glass is easy to clean and keep clean translucent glass to avoid soot particles adhered to affectlighteffect.
