GB2406-2009 Digital-readout Oxygen Index Tester

Product description: Digital-readout oxygen index tester is used to test the required oxygen concentration (volume percent) in the process of polymer burning. Polymer OI value is the min oxygen volume percent of the required oxygen and nitrogen gas mixture in the process of this material is able to be kept burning for 50 mm or 3 minutes once being ignited. Standard: • GB2406-2009 Features: • Simple structure, and easy operation • It is a tool to identify the polymer burning performance, as well as a tool of the related research, thereby, we can get a better understanding of the polymer burning • Applied to test the property of plastic, rubber, forth etc • The test result is accurate and with very good reappear function, therefore, it’s an essential testing instrument for researching and producing flame-resistant materials Technical parameters: • Internal diameter of the combustor: 100mm • Height of the combustor: 450mm • Pipe hole diameter of the long pole igniter trailing end ￠2±1mm • Flowmeter: 160~1600L/H adjustable • Precision of the pressure gauge: level 2.5 • Resolution of the pressure gauge: 0.01Mpa • Resolution of the Oxygen concentrate indicator: 0.1% • Oxygen sensor: imported from Germany with high precision • Gas source: the GB3863 specified oxygen, the GB3864 specified nitrogen • Experiment environment: temperature: 10~35℃, humidity: 45-75% • Input pressure: 0.2-0.3Mpa • Working pressure: 0.05-0.15Mpa • Sample type: self-supporting materials and non-self-supporting materials • Oxygen index die: 10mm×100mm Specifications: • Overall dimensions: 700mm(W)×400mm(D)×600mm(H) • Power supply: AC220V, 50/60Hz 5A • Air source: oxygen, nitrogen( prepared by users)
