HZ-7022 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 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.
HZ-7022 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.
