GB17761 Smoke Density Testing Machine for Combustion or Decomposition of Building Materials

1、 Overview:

GB17761 Smoke Density Tester for Building Materials, used to measure the static smoke density of building materials under combustion or decomposition test conditions. Smoke density testing is conducted by measuring the loss of luminous flux in the test chamber, and phenomena such as flames and smoke can be observed during the test period.
