Limiting Oxygen Index Test Apparatus Plastic Rubber Foam Limiting Oxygen Index Tester

Limiting Oxygen Index Test Apparatus Plastic Rubber Foam Limiting Oxygen Index Tester

Main Technical Parameter:

1. Adopt imported oxygen sensor, oxygen concentration can be digital displayed without calculation.the accuracy is higher and more accurate, the range is 0-100%

2. Digital resolution: ±0.1%

3. Measurement accuracy: 0.1 level

4. The touch screen setting program automatically adjusts the oxygen concentration

5. One-click calibration accuracy

6. One-click concentration ratio

7. Automatic alarm sound when the oxygen concentration is stable

8. With timing function

9. Can store experimental data

10. Can query historical data

11. Can clear historical data

12. Can choose whether to burn 50mm

13. Air source failure prompt

14. Oxygen sensor fault prompt

15. Prompt for wrong connection of oxygen and nitrogen

16. Oxygen sensor aging tips

17. Standard oxygen concentration input

18. The diameter of the combustion tube can be set (two common specifications are available)

19. Flow adjustment range: 0-20L/min (0-1200L/h)

20. Quartz glass tube: 75cm (can be customized according to user requirements)

21. Gas velocity in the combustion tube: 40mm±2mm/s

22. Overall dimensions: 650mm×400×830mm (can be customized according to user requirements)

23. Pressure gauge accuracy level 2.5, resolution: 0.01MPa

24. Test environment: ambient temperature: room temperature ~ 50 ℃;relative humidity: ≤70%;

25. Input pressure: 0.05-0.3MPa

26. Working pressure: nitrogen 0.15-0.20Mpa oxygen 0.15-0.20Mpa

27. The sample holder can be used for soft and hard plastics, various building materials, textiles, fire doors, etc.

28. Propane (butane) ignition system, the ignition nozzle is made of a metal tube, and the end has a nozzle with an inner diameter of Φ2±1mm, which can be bent freely. Can be inserted into the combustion tube to ignite the sample, flame length: 16±4mm, size 5mm-60mm can be adjusted freely,

29. Gas: Nitrogen and oxygen for industrial use, purity>99%; (user-provided/regular gas station industrial oxygen purity is generally between 99.2%-99.3%).

30. Power requirements: AC220 (+10%) V, 50HZ

31. Maximum power consumption: 150W

32. Self-supporting material sample clamp: can be fixed on the axis of the combustion cylinder and can clamp the sample vertically

33. Non-self-supporting material sample holder: can fix the two vertical sides of the sample to the frame at the same time (optional/applied to soft and non-self-supporting materials such as textiles)

Advantage:

• Full-color touch screen control, just set the oxygen concentration value on the touch screen,

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;

• The stepped proportional valve is used to greatly improve the control accuracy of the flow

rate. The closed-loop control is adopted. The oxygen concentration drift program is automatically adjusted back to the target value during the test, avoiding the disadvantage that the traditional oxygen index meter cannot adjust the oxygen concentration during the test. Improve test accuracy.

Application:

It is suitable for the determination of the combustion properties of materials such as plastics,rubber, fibers, foams, films and textiles, that is, the concentration percentage of the lowest oxygen in which the polymer just maintains combustion.

Applicable standards:

ASTM D 2863, ISO 4589-2, NES 714, GB/T 5454 GB/T 10707 GB/T 8924-2005 GB/T 16581-1996NB/SH/T 0815-2010 TB/T 2919-1998 IEC 61144-1992 ISO 15705-2002 ISO 4589-2-1996
