JF-6 Fully Automatic High Precision Oxygen Index Tester Touchscreen Control

1Product functional features

1. Full color touch screen control, simply set the oxygen concentration value on the touch screen, and the program will automatically adjust to the oxygen concentration balance and emit a beep sound prompt, eliminating the trouble of manually adjusting the oxygen concentration; One click calibration of oxygen concentration, data storage

2. The step proportional valve is used to greatly improve the flow control accuracy. The closed-loop control is used to automatically adjust the oxygen concentration drift program 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;

3. The equipment comes with a fume hood that can automatically exhaust smoke;
