Main Features:    
1, Imported paramagnetic oxygen oxygen concentration sensor.
2, The oxygen index meter is equipped with a high temperature quartz glass column, the opening DIAM. of column cap is 40mm.
3. The LOI meter is supplied with samples holders for physically self-supporting specimens and supported film or sheet test specimens,
4. Mass flow controller automatically adjusts oxygen and nitrogen gas flow rate according to set concentration.
5. The patented gas flow mixing control unit is equipped with nitrogen and oxygen mass flow controllers to precisely control the gas flow.
6. After the oxygen concentration is set on the screen, the PLC touch screen control system will automatically adjust the oxygen concentration according to the set value. Accurate and convenient;
7. Patented gas mixing chamber ensures more accurate determination of oxygen concentration and more sufficient mixing of oxygen and nitrogen
8.The color LCD touch screen displays the parameters of flow, time and test results in real time.
9. The limited oxyen index tester is equipped with special igniter, easy to operate.

Control System:
1,PLC and touch screen make the test more automatic.
2, After the oxygen concentration value is set, the system automatically adjusts the oxygen concentration.
3,The key electrical components are imported, accurate, reliable and durable;
4, The oxygen index tester is equipped with an automatic calibration system to avoid the influence of the oxygen sensor drift due to the environmental impact on the test results.
5.One button automatic calibration system, convenient and fast, avoid the trouble of regular calibration.
