GAS DRAWING PUMP TO DETERMINE SMOKE TOXICITY

Used to determine the specific optical density of smoke generated by a solid sample up to 25mm in vertical position. A radiant heat source and a 6-flame burner simulate both test conditions at the same time, radiation and combustion. While the smoke generated by the sample is kept in an air chamber, a photometric system determines the transmission variations. The test data and the optical density specified are displayed on a personal computer.
