ISO 4589-2 ASTM D2863 Limited Oxygen Index Apparatus with Smoke Density Tester
Application:
Limited Oxygen Index with Smoke Density Tester is designed according to ISO4589.1-2006, it applies to analysis the minimum oxygen concentration needed to maintain combustion of the sample when the sample is under the test conditions specified in oxygen and nitrogen mixed gas;
This tester is installed with England imported oxygen sensor, and automatic control the oxygen and nitrogen flow with mass flow control meter. It is very easily and quickly to operate; It is used for evaluating homogeneity of solid materials, laminates, foam, film and thin film in the specified conditions of flammability.
