Brief introduction: Critical oxygen burning tester can test samples need the minimum concentration of oxygen. Oxygen index is measured material flame retardant features an important reference value. Oxygen index refers to a certain size of material specimens () loading test device, under prescribed conditions, into the mixture of oxygen and nitrogen, the specimens will be lit with torches, determine the minimum necessary to keep burning oxygen concentration (in percentage). This tester is for the import of paramagnetic oxygen concentration sensor, measurement accuracy, long life, low error rate and high reliability. Features: 1. The British Servomex paramagnetic oxygen concentration sensor, display precision of oxygen concentration of plus or minus 0.1%. 2. Equipped with 2 sets of mass flow controller (MFC), to control nitrogen, oxygen, mix proportion, Control precision and convenient 3. Compared with traditional electrochemical oxygen sensor, no life limit (electrochemical oxygen sensors Oxygen sensor often need to change the battery), higher precision, faster response time. 4. Equipped with high temperature resistant quartz glass tube 5. Equipped with can support and without support the sample holder 6. Portable igniter, equipped with quick connector, precision needle valve adjusted by flame size. 7. Digital set nitrogen, oxygen concentration, without artificial adjusted again and again. 8. Desktop PC + professional LABVIEW software operation, control of oxygen and nitrogen mixture ratio, Technical parameters: Oxygen concentration measurement range: 0-100% Resolution: 0.1% Accuracy of measurement: plus or minus 0.4% Response time: < 6 s
