LR-A029 ISO4589-2 ASTM D2863 Oxygen Index Tester

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 give a sound hint of the di, avoiding the trouble of manually adjusting the oxygen concentration;

2. The step ratio valve is adopted to greatly improve the flow control accuracy, and the closed-loop control is adopted. During the test, the oxygen concentration drift program is automatically adjusted back to the target value, which avoids the disadvantages of the traditional oxygen index tester that cannot adjust the oxygen concentration in the test and greatly improves the test accuracy.

1. Imported oxygen sensor is adopted to display the oxygen concentration without calculation, with higher accuracy and more accuracy, and the range is 0-100%

2. Digital resolution: plus or minus 0.1%

3. Measurement accuracy: 0.1 level

4. Set the touch screen program to adjust the oxygen concentration automatically

5. Precision of one-button calibration

6. One bond concentration

7. Automatic alarm sound with stable oxygen concentration

With timing

9. Experimental data can be stored

10. Historical data can be queried

11. Historical data can be cleared

12. Whether to burn 50mm or not is optional
