Digital Oxygen Index Tester

1. Adopting imported oxygen sensor, digital display of oxygen concentration without calculation, higher and more accurate precision, range 0-100%.
2. Flow rate adjustment range: 0-10L/min (60-600L/h)
3. Combustion cylinder: inner diameter ≥ 75 ㎜ height 400mm
4. Pressure gauge precision 2.5 grade, resolution: 0.01MPa
5. Oxygen/nitrogen mixed gas inlet: including pressure regulator valve, flow regulator valve, gas filter and mixing chamber.
6. Propane (butane) ignition system, flame length 5mm-60mm freely adjustable
7. Igniter: made of a metal tube with a nozzle of inner diameter Φ2±1mm at the end, which can be inserted into the combustion cylinder to ignite the specimen, flame length: 16±4mm, adjustable in size.
8.Digital resolution: ± 0.1%
9. Measurement accuracy: 0.4 level
10. Response time: <5S
11. Gas flow rate in the combustion cylinder: 40mm ± 10mm / s
12. Flow meter: 1-15L/min (60-900L/H) adjustable
13. Specimen clamps can be used for soft and hard plastics, textiles, fire doors, etc.
14. Gas: industrial nitrogen, oxygen, purity > 99%; (user-provided)
15. Self-supporting material specimen clamp: it can be fixed in the position of the axis of the burning cylinder and can clamp the specimen vertically.
