Intelligent Automatic Touch-Screen Control Oxygen Index Tester
I. Intelligent Full-automatic Touch Screen Control Oxygen Index Tester Product Advantages:
1. Full-color touch screen control, simply set the oxygen concentration on the touch screen, the program will automatically adjust to the oxygen concentration balance and emit a squeaking sound prompt, eliminating the need to manually adjust the oxygen concentration；
2. The use of stepping proportional valves has greatly improved the flow control accuracy. Closed-loop control is used. During the test, the oxygen concentration drift program is automatically adjusted back to the target value, avoiding the disadvantages of the traditional oxygen index analyzer not adjusting the oxygen concentration in the test. Improve the test accuracy.

ASTM D 2863, ISO 4589-2, ISO 4589-3, NES 714, NES 715
Tips: Oxygen index tester requires not less than 98% of each industrial-grade oxygen/nitrogen bottle as the gas source. Because the above gas is a high-risk transport product, it cannot be provided as an oxygen index analyzer fitting, and it can only be used locally by users. Gas station purchase. (To ensure the purity of the gas, please purchase it at the local regular gas station)
What is oxygen Index test?
Measuring the Minimum Oxygen Concentration to Support Candle-Like Combustion of Plastics (Oxygen Index) ASTM D2863. Scope: ASTM D2863 is a method to determine the minimum concentration of oxygen in an oxygen/nitrogen mixture that will support a flaming burn in a plastic specimen.
