oxygen indexer testing machine

The high temperature oxygen index tester is designed and de-veloped according to ISO4589-3 (Elevated-temperature test) and British Naval Engi-neering Standard NES 715. Based on the general intelligent oxygen index instrument,the high temperature oxygen index tester adds a electric-heating device at the position of the combustion cylinder to preheat the mixed gas and test the ignition temperature of the different materials at a certain oxygen concentration.
