Product Introduction
TESTech Limit Oxygen Index 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 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; Used for evaluating homogeneity of solidmaterials, laminates, foam, film and thin film in the specified conditions of flammability.
