Tips: The oxygen index tester needs to use not less than 98% of industrial grade oxygen/nitrogen as a gas source. Since the above gas is a high-risk transport product, it cannot be provided as an accessory of the oxygen index tester. Gas station purchase. (To ensure the purity of the gas, please purchase it at the local gas station)

The JF-3 oxygen index tester is a new model developed according to the technical requirements of the national standard GB/T2406.
The instrument is used to determine the volume percentage of oxygen required during the combustion of the polymer. The polymer oxygen index value is the oxygen and nitrogen mixed gas stream required to maintain a combustion length of 50 mm or a combustion time of 180 s after the material is ignited. The minimum oxygen concentration (also known as the oxygen index) required to maintain the pattern burning.
