LR-JF-6 Full-automatic high-precision oxygen index tester touch screen control

Product advantages:

1. Full-color touch screen control, as long as the oxygen concentration value is set on the touch screen, the program will automatically adjust to the oxygen concentration balance and issue the sound of beep, eliminating the trouble of manually adjusting the oxygen concentration;One key calibration oxygen concentration, data storage
2. The stepping proportional valve is adopted to greatly improve the control accuracy of flow rate. The closed-loop control is adopted to automatically adjust the oxygen concentration drift program back to the target value during the test.
3. The equipment has its own fume hood, which can automatically exhaust smoke;

The main technical parameters of jf-6 automatic high precision oxygen index tester are controlled by touch screen (with fume hood)
