Oxygen index meter

The JF-3 digital oxygen index analyzer is an accurate, reproducible, convenient and fast detection instrument for measuring the combustibility of polymers.Oxygen index meterNot only can it be used as a means of identifying the flame retardancy of polymers, but it can also serve as a research tool.
The JF-3 digital oxygen index analyzer is a new product developed according to the technical requirements specified in the national standard GB/T2406.
This instrument is used to determine the volume percentage of oxygen required during the combustion process of polymers. The polymer oxygen index value is the low oxygen concentration (also known as the oxygen index) required to maintain combustion for 50mm or 180s in the oxygen nitrogen mixture airflow after the substance is ignited.
