Intelligent automatic touch screen controlled oxygen index meter
Ⅰ.Product Features
1. Full-color touch screen control, just set the oxygen density value on the touch screen, the program will automatically adjust to the oxygen concentration balance and give the sound of beep prompt, It avoids the disadvantage that the traditional oxygen index meter can not adjust the oxygen concentration in the test, and greatly improves the test accuracy.
2. The step proportional valve is adopted to greatly improve the control accuracy of flow, and the closed-loop control is adopted to automatically adjust the oxygen concentration drift program back to the target value in the test, avoiding the disadvantage that the traditional oxygen index tester cannot adjust the oxygen concentration in the test and greatly improving the test accuracy.
Ⅱ. Function
1.Imported oxygen sensor is adopted to display oxygen concentration without calculation, with higher and more accurate accuracy and range from 0 to 100%
2.One key calibration accuracy
3. One bond ratio concentration
4. Stable oxygen concentration automatically prompts the alarm sound
5. With timing function
6. Experimental data can be stored
7. Historical data can be queried
8. Historical data can be erased
9. Choose whether to burn 50mm
10. Air source fault indication
11. Oxygen sensor fault indication
12. Oxygen nitrogen misconnection indication
13. Oxygen sensor aging tips
14. Standard oxygen concentration input
15. Diameter of combustion cylinder can be set (two common specifications are optional)
16. Self-supporting material sample holder: can be fixed at the center of the combustion cylinder and can be vertically clamped to the sample
17. Non-self-supporting material sample holder: two vertical edges of the sample can be fixed to the frame at the same time (optional/applicable to soft non-self-supporting materials such as textiles)
