Intelligent automatic touch screen control oxygen index meter
I. intelligent full-automatic touch-screen control oxygen index tester
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.
Ii. Main technical parameters of intelligent full-automatic touch screen control oxygen index meter
1. Imported oxygen sensor is adopted to display the oxygen concentration without calculation, with higher accuracy and a range of 0-100%
2. Digital resolution: ±0.1%
3. Measurement accuracy: level 0.1
4. Touch screen Settings automatically adjust oxygen concentration
5. One-key calibration accuracy
6. One-key ratio concentration
7. Automatic alarm sound for stable oxygen concentration
8. With timing function
9. Experimental data can be stored
10. Historical data can be queried
11. Historical data can be cleared
12. 50mm combustion is optional
13. Indication of air source fault
Failure indication of oxygen sensor
15. Wrong connection of oxygen and nitrogen is indicated
16. Indication of oxygen sensor aging
17. Standard oxygen concentration input
18. Combustion cylinder diameter can be set (two common specifications are optional)
19. Flow regulation range: 0-20l /min (0-1200l /h)
20. Quartz glass cylinder: choose one of two specifications (inner diameter ≥ 75mm or inner diameter ≥ 85mm)
21. Gas velocity in combustion tube: 40mm±2mm/s
22. Overall dimension: 650mm×400×830mm
23. Pressure gauge accuracy class 2.5, resolution: 0.01MPa
24. Test environment: ambient temperature: room temperature ~ 40℃;, relative humidity: ≤70%;
25. Input pressure: 0.25-0.3mpa
26. Working pressure: nitrogen 0.15-0.20mpa and oxygen 0.15-0.20mpa
27. Sample holder can be used for soft and hard plastics, all kinds of building materials, textiles, fire doors, etc
28. Propane (butane) ignition system, the ignition nozzle is made of a metal, the end has Φ 2 + / - 1 mm inner diameter nozzle, can be bent freely.Can be inserted into the combustion tube to ignite the sample, the flame length: 16±4mm, the size of 5mm to 60mm can be freely adjusted,
29. Gas: industrial nitrogen and oxygen, purity > 99%;(the purity of industrial oxygen of user-provided/regular gas stations is generally between 99.2% and 99.3%).
30. Power requirements: AC220 (+10%) V, 50HZ
31. Maximum power: 150W
32. Self-supporting material sample holder: it can be fixed on the axial position of the combustion cylinder, and can hold the sample vertically
33. Non-self-supporting material sample holder: two vertical edges of the sample can be fixed on the frame at the same time (optional/applied to soft non-self-supporting materials such as textiles).
Iii. Design standard: GB/T 2406.2-2009
Tips: each bottle of industrial-grade oxygen/nitrogen shall be used as the air source during the test of the oxygen index tester. As the above gases are high-risk transportation products, they cannot be provided as the accessories of the oxygen index tester. They can only be purchased at the user's local gas station.(in order to ensure the purity of gas, please purchase from the local regular gas station)
