Introduction: This automatic oxygen index tester meets the requirements of ISO4589, GB/T2406, and GB/T5454 standards, and is mainly used to determine the volume percentage of oxygen required during the combustion of polymers; this equipment can not only be used as a means to identify the flame retardancy of polymers It can also be used as a research tool to provide powerful testing methods for the laboratory to study flame-retardant formulations and develop new flame-retardant materials. The equipment is easy to use and reliable. The test system uses imported oxygen sensors and displays the results digitally. Features: 1. Color programmable controller, directly set the required oxygen concentration 2. Imported paramagnetic oxygen sensor, no need to replace, long-term use saves costs 3. Oxygen and nitrogen trace proportional valve control, high precision, no deviation 4. USB data printing interface, test data can be directly generated in EXCEL format 5. Foot-operated test program control, single person completes all tests independently 6. Equipped with high temperature resistant disposable molded quartz glass cylinder 7. Equipped with supportable and unsupported sample holder 8. Equipped with two ignition methods: internal control igniter and handheld igniter 9.
