Oxygen Index Meter (Digital Display)

• Scope of application:

It is suitable for the determination of the combustion performance of materials such as plastics, rubber, fibers, foamed plastics, soft sheets and films, and textiles

• The main technical parameters:

1. Imported oxygen sensor is used, the digital display of oxygen concentration does not need to be calculated, the precision is higher and more accurate, and the range is 0-100%

2. Digital resolution: ±0.1%

3. Machine measurement accuracy: 0.4 level

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

5. Response time: <5S

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

7. Gas flow rate in the combustion tube: 40mm±2mm/s

8. Pressure gauge precision 2.5, resolution: 0.01MPa

9. Flow meter: 1-15L/min (60-900L/H) adjustable, precision 2.5

10. Test environment: ambient temperature: room temperature ~ 40 ° C;, relative humidity: ≤ 70%;

11. Input pressure: 0.2-0.3MPa

12. 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.

13. Specimen holders for soft and rigid plastics, textiles, fire doors, etc.

14. Propane (butane) ignition system, flame length 5mm-60mm can be adjusted freely

15. Gas: Nitrogen and oxygen for industrial use, purity>99%; (users prepare by themselves).

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

17. Maximum use power: 50W

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

19. Self-supporting material sample clamp: it can be fixed on the axis of the combustion tube and can clamp the sample vertically

20. Non-self-supporting material sample clamp: can fix the two vertical sides of the sample on the frame at the same time (optional textile film and other materials are applicable)

• Chassis and part structure:

1. Control box: It is processed and formed by CNC machine tools. The steel plate spray box is electrostatically sprayed. The control part and the test part are controlled separately.

2. Combustion cylinder: high temperature resistant high-quality quartz glass tube (inner diameter ￠75mm, length 480mm) outlet inner diameter: φ40mm

3. Sample fixture: self-supporting fixture, and can clamp the sample vertically; (non-self-supporting sample rack is optional), two sets of sample clips meet different test requirements; sample clip plug-in type, place the sample Easier with style clips

4. The diameter of the tube hole at the end of the long rod igniter is ￠2±1mm, and the flame length of the igniter (5-50) mm can be adjusted arbitrarily

• Design standard: GB/T 2406.2-2009

Tips: The oxygen index tester needs to use a bottle of not less than 98% industrial-grade oxygen and nitrogen as the gas source. Since the above gases are high-risk transport items, they cannot be provided as accessories for the oxygen index tester. They can only be provided locally. Gas station purchase. (To ensure the purity of the gas, please purchase it at a local regular gas station)
