It is used to determine the oxygen concentration (volume percentage) required by the polymer in the combustion process. The instrument has a simple structure and is easy to operate. It is measured by a sensor (imported), and the result is displayed digitally without calculation by formula. This machine can be used as a means to identify the combustion performance of polymers, and can also be used as a related research tool to gain a better understanding of the combustion process of polymers.

ASTM D 2863, ISO4589-2
Overview:
It is used to determine the oxygen concentration (volume percentage) required by the polymer in the combustion process. The instrument has a simple structure and is easy to operate. It is measured by a sensor (imported), and the result is displayed digitally without calculation by formula. This machine can be used as a means to identify the combustion performance of polymers, and can also be used as a related research tool to gain a better understanding of the combustion process of polymers.
Use:
This instrument is suitable for testing the combustion properties of plastic, rubber, foam and other materials, and its measurement results are accurate and reproducible. It is an indispensable testing equipment for the research and production of flame retardant materials.
Definition：
The oxygen index tester refers to the minimum oxygen concentration required for a material to burn flamingly in an oxygen-nitrogen mixed flow under specified conditions. It is expressed as the numerical value of the volume percentage of oxygen. A high oxygen index indicates that the material is not easy to burn, and a low oxygen index indicates that the material is easy to burn. It is generally believed that the oxygen index <22 belongs to flammable materials, the oxygen index between 22-27 belongs to combustible materials, and the oxygen index >27 belongs to flammable materials.
