Digital Oxygen Index Analyzer
Product Name: Digital Oxygen Index Tester
TIPS: Digital Oxygen Index Tester with temperature controller to
control temperature, the other parameters are consistent with JF-3
type digital oximetry index analyzer.
First, the scope of application:
Suitable for the determination of the burning properties of
plastics, rubber, fiber, foam, film and film and textile materials
Second, the main technical parameters:
1. Using imported oxygen sensor, the digital display shows the
oxygen concentration without calculation, the accuracy is higher
and more accurate, the range is 0-100%
2. With temperature controller to control temperature, control
range: 23 ° C ± 2 ° C
3. Digital resolution: ±0.1%
4. Measurement accuracy: 0.4
5. Flow adjustment range: 0-10L/min (60-600L/h)
6. Response time: <5S
7. Combustion tube: inner diameter ≥75mm high 400mm
8. Gas flow rate in the combustion cylinder: 40mm ± 2mm / s
9. Pressure gauge accuracy 2.5, resolution: 0.01MPa
10. Flowmeter: 1-15L/min (60-900L/H) adjustable, test environment:
ambient temperature: room temperature ~ 40 °C;, relative humidity:
≤ 70%;
11. Input pressure: 0.2-0.3MPa
12. Working pressure: nitrogen 0.1-0.15Mpa Oxygen 0.1-0.15Mpa
Oxygen/nitrogen mixed gas inlet: including pressure regulator
valve, flow regulating valve, gas filter and mixing chamber.
13. Sample holders can be used for soft and rigid plastics,
textiles, fire doors, etc.
14. Propane (butane) ignition system, flame length 5mm-60mm can be
adjusted freely
15. Gas: industrial nitrogen, oxygen, purity >99%;
(user-supplied).
16. Power requirements: AC220 (+10%) V, 50HZ
17. Maximum operating power: 50W
18. Ignition: There is a metal tube with a nozzle with an inner
diameter of Φ2±1mm at the end. It can be inserted into the
combustion tube to ignite the sample. The flame length is 16±4mm,
and the size can be adjusted.
19. Self-supporting material sample holder: can be fixed at the
axial position of the combustion tube and can clamp the sample
vertically
20. Non-self-supporting material sample holder: can fix two
vertical sides of the sample to the frame at the same time
Third, the chassis and part of the structure:
1. Control box: It is processed by CNC machine tool, electrostatic
spraying, beautiful, anti-rust and anti-corrosion. Control part and
test part are controlled separately
2. Combustion tube: high temperature resistant high quality quartz
glass tube (inner diameter ¢75mm, length 300mm) Outlet diameter:
φ40mm
4. Mixer: Mix the oxygen and nitrogen evenly with a glass bead
filler. (Bead φ4.5mm filling height 95mm, one bag)
5. Specimen fixture: self-supporting clamp, and can clamp the
specimen vertically; (optional non-self-supporting style bracket),
two sets of clamps meet different test requirements; style clamp
plug-in type, placement style Easier with style clips
7. The standard is equipped with a glass tube to prevent accidental
damage and meet the requirements of uninterrupted test; the
diameter of the end of the long rod igniter is ±2±1mm, and the
length of the igniter flame (5-50)mm can be adjusted freely.
Forth, Design standard: GB/T 2406.2-2009 GB/T 2406.1-2008
Compliance with standards: ASTM D 2863, ISO 4589-2, NES 714 GB/T
