Smoke Limited Oxygen Index  

Model No.

 HF-3 Smoke Limited Oxygen Index  


HF-3 Smoke Limited Oxygen Index 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.

 Related Standards:


GB/T 2406.2

ASTM D2863

NES 714

ISO 4589-2

Note: the Smoke Limited Oxygen Index can conform to but not limit to all the standards above, for more standards conformance, please contact us.
