Meet standards:
According to the national standard GB2406 stipulated conditions of manufacture of an instrument.
Product summary:
This Oxygen index tester used to determine the polymer to the desired oxygen concentration (volume percent) in the combustion process. The instrument is simple, easy to operate, through the sensor (import) measurement, the figures showthe results,do not have to be calculated by the formula. This machine can be used as combustion performance as a means of identification of polymer can be used as a research tool in order to obtain a better understanding of the combustion process of the polymer.
Applicable industry:
This Oxygen index tester applies to the burning of plastics, rubber, foam and other materials performance test, its results are accurate, the reproducibility is good. Research, test equipment essential for the production of flame retardant material.
Defined:
The Limiting Oxygen Index Tester under the conditions specified, the materials in the minimum oxygen concentration required for combustion of oxygen and nitrogen mixed gas stream. To represent the oxygen percentage of the volume occupied by the value. The oxygen index is high that the material is nonflammable, low oxygen index of said material is highly flammable and is generally believed that the oxygen index of <22 is a flammable material, oxygen index between 22 --- 27 is a combustible material, oxygen index> 27 is a flame retardant materials.
