Meet standards:
Limited Oxygen Index Test Instrument meet according to the national standard GB2406 stipulated conditions of manufacture of an instrument.
Product summary:
Limited Oxygen Index Test Instrument 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 show the 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:
Limited Oxygen Index Test Instrument 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:
Limited Oxygen Index Test Instrument 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.
