1. Full-color touch screen control. You only need to set the oxygen concentration value on the touch screen, and the program will automatically adjust to the oxygen concentration balance and sound prompt.
2. The step proportional valve is adopted to greatly improve the accuracy of flow control, and the closed-loop control is adopted to automatically adjust the oxygen concentration drift program back to the target value during the test, which avoids the disadvantage that the traditional oxygen index tester cannot adjust the oxygen concentration during the test and greatly improves the test accuracy.
