The Oxygen index tester is used to evaluate the combustion performance of polymers under specified test conditions, that is, to determine the volume percentage concentration of low oxygen at which the polymer just maintains combustion.

 

 

1. Using imported oxygen sensor, digital display of oxygen concentration does not need to be calculated, the accuracy is higher and more accurate, the range is 0-100 baifenhao

 

2. Digital resolution: ±0.1%

 

3. Display accuracy: 0.4 level

 

4. Flow adjustment range: 0-10L/min (60-600L/h)

 

5. Response time: <5S

 

6. Quartz glass cylinder: inner diameter ≥75mm high 480mm

 

7. Gas flow rate in the combustion tube: 40mm±10mm/s, the total height of the combustion tube is 450mm

8. The accuracy of the pressure gauge is level 2.5, resolution: 0.01MPa

 

9. Flow meter: 1-15L/min (60-900L/H) adjustable, test environment: ambient temperature: room temperature ~ 40℃; relative humidity: ≤70%;

 

10. Input pressure: 0.2-0.3MPa

 

11. Working pressure: Nitrogen 0.05-0.15Mpa Oxygen 0.05-0.15Mpa Oxygen/nitrogen mixed gas inlet: including pressure stabilizing valve, flow regulating valve, gas filter and mixing chamber.

 

12. The sample holder can be used for soft and hard plastics, textiles, fire doors, etc.

 

13. Ignition system, flame length 5mm-60mm can be adjusted freely

 

14. Gas: Nitrogen and oxygen for industrial use, with a purity of >99%; (provided by the user).

 

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

 

16. Use power: 50W

 

17. Igniter: It is made of a metal tube and has a nozzle with an inner diameter of Φ2±1mm at the end, which can be inserted into the combustion tube to ignite the sample. The flame length: 16±4mm, the size is adjustable

 

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

 

19. Non-self-supporting material sample holder: can fix the two vertical sides of the sample on the frame at the same time
