Digital oxygen index tester

(The box material is divided into steel plate electrostatic spraying and frosted stainless steel two prices have a cost difference of 500 yuan. If you need to order, please confirm the price in advance)

First, scope of application                                           

Applicable to plastics, rubber, fiber, foam, film and textile materials such as combustion performance measurement

Second, relevant technical parameters                                       

1. Imported oxygen sensor, digital display oxygen concentration without calculation, higher accuracy and more accurate, range 0-100%
2. Digital resolution: ±1%
3. The measuring accuracy of the whole machine: 0.4
4. Flow adjustment range: 0-10L/min (60-600L/h)
5. Response time: < 5S
6. Quartz glass cylinder: inner diameter ≥75㎜ high 480mm
7. Gas flow rate in combustion cylinder: 40mm±2mm/s
8. Pressure gauge accuracy level 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℃; , 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 regulator, flow regulator, gas filter and mixing chamber.
13. Sample clips can be used for soft and hard plastics, textiles, fire doors, etc
14. Propane (butane) ignition system, flame length 5mm-60mm can be freely adjusted
15. Gas: industrial nitrogen, oxygen, purity > 99%; (Note: air source and link head user's own).

Tips: When the oxygen index tester is tested, it is necessary to use not less than 98% of the industrial grade oxygen/nitrogen each bottle as the air source, because the above gas is a high-risk transport goods, can not be provided as the oxygen index tester accessories, can only be purchased in the user's local gas station. (In order to ensure the purity of the gas, please purchase in the local regular gas station)

16. Power requirements: AC220 (+10%) V, 50HZ
17. Maximum operating power: 50W
18. Igniter: There is a nozzle made of a metal tube 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, the size is adjustable
19. Self-supporting material sample clip: can be fixed in the combustion cylinder axis position, and can vertically clamp the sample
20. Non-self-supporting material sample clip: can fix two vertical sides of the sample on the frame at the same time (optional textile film and other materials applicable)

Third, chassis structure                                       

1. Control box: CNC machine tool processing molding, steel spray box electrostatic spraying, control part and test part separate control.
2. Combustion cylinder: high temperature quartz glass tube (inner diameter ￠75mm, length 480mm) Outlet inner diameter: φ40mm
3. Sample fixture: self-supporting fixture, and can hold the sample vertically; (optional non-self-supporting style frame), two sets of style clips to meet different test requirements; Style clip splice type, placing style and style clip more simple
4. Long rod igniter tail pipe hole diameter ￠2±1mm, igniter flame length (5-50) mm can be adjusted atwill

Fourth, applicable standard
