Building Material Smoke Density Testing machine

In the event of fire, people are choked by smoke or can not escape because they can not see the road. Therefore, in the prevention of fire, it is very important to accurately test the smoke density of the material .
This building materials smoke density tester meets all the technical parameters and requirements specified in the GB GB / T8627-2007,  and can be used to measure and describe the heat and flame response of  materials, products and components under a controlled laboratory condition. Measuring the static smoke production of building materials under the test conditions of combustion or decomposition is extremely important for predicting fire hazards
