Introduction: Meet the standards: ISO4589-2, ASTM D2863, GB/T2406, GB/T5454, JT/T1095-2016 Principle: Fix a sample in a transparent combustion tube of an oxygen and nitrogen mixed gas flowing upward, ignite the top of the sample, observe the burning characteristics of the sample, and continuously burn the sample or the length of the sample. The minimum value of the oxygen concentration is estimated by a series of tests at different oxygen concentrations compared to the given criteria. Field of application: The method for determining the minimum oxygen concentration required to maintain the combustion of a sample in an oxygen-nitrogen mixed gas under specified experimental conditions, the result of which is defined as the oxygen index. It is used to measure the combustion properties of various textiles, including woven, knitted, non-woven fabrics, etc. It can also be used for the determination of the burning properties of plastics, rubber, paper and the like. Features: 1. Color programmable controller, directly set the required oxygen concentration 2. Imported paramagnetic oxygen sensor, can be used for a long time without replacement 3. Oxygen and nitrogen micro-proportional valve control, high precision, no deviation 4.USB data interface, test data directly generated EXCEL format 5. Foot-operated test program control, single person completes all tests independently 6. Equipped with high temperature resistant one-time forming quartz glass tube 7. Equipped with supportable and unsupported specimen holders 8. Equipped with two ignition methods: 9. Internal control igniter, hand-held igniter Technical Parameters: Model: 5801A Outer size: 410*510*830 Measuring range: 0-100% Working pressure: 0.05 -0.3 Mpa. Burning cylinder height: 500mm Burning cylinder inner diameter: 76mm The top of the burner tube is limited to Φ 40mm. Combustion tube flow rate (40 ± 2) mm / s.
