JF-3 Digital Oxygen Index Tester Introduction
JF-3 type digital oximetry index instrument is also called oxygen index meter, oxygen index detector, oxygen index meter, according to national standard GB/T5454-1997 "Textile burning performance test method oxygen index method", GB/T2406-1993 A new product developed by the technical requirements of the "Plastics Burning Performance Test Method Oxygen Index Method". The Digital Oxygen Index Tester is suitable for testing the burning properties of homogeneous solid materials, laminates, foams, fabrics, films and films. The digital oxymaginometer is mainly used to determine the percentage of oxygen required for the combustion process of a polymer. It can be used as a means to identify the flame retardancy of a polymer, and it can also be used as a research tool - laboratory research flame retardant formula.
