DRK304B Digital Display Oxygen Index Meter

The DRK304B digital oxygen index meter is a new product developed according to the technical requirements specified in the national standard GB/T2406-2009. It is suitable for the combustion performance test of homogeneous solid materials, laminated materials, foam plastics, fabrics, flexible sheets and films. . This instrument is used to determine the percentage of oxygen required for the polymer combustion process. The product can be used as a means to identify the flame retardancy of polymers, and it can also be used as a research tool-laboratory research on flame retardant formulations.

The instrument uses imported high-precision sensors, which can be displayed digitally, with high accuracy and good reproducibility of test data.
