DRK-60B Digital Oxygen Index Analyzer

Product details

Product Application

It is suitable for the determination of combustion properties of plastics, rubber, fibers, foam plastics, film and textile materials.

Technical Parameters

1. Using imported oxygen sensor, the digital display of oxygen concentration does not need to be calculated. The accuracy is higher and more accurate, ranging from 0% to 99%.

2. Digital resolution: +0.1%

3. Measurement accuracy of the whole machine: 0.4 grade

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

5. Response time: <5S

6. Quartz glass cylinder: inner diameter (> 75) 300 mm high

7. Gas flow rate in the combustion cylinder: 40mm+10mm/s combustion cylinder total height 450mm

8. Pressure gauge accuracy 2.5, resolution: 0.01MPa

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

10. Test environment: ambient temperature: room temperature to 40 C; relative humidity: <70%;

11. Input pressure: 0.2-0.3 MPa

12. Working Pressure: Nitrogen 0.05-0.15Mpa Oxygen 0.05-0.15Mpa Oxygen/Nitrogen Mixture Inlet: Including Pressure Regulating Valve, Flow Regulating Valve, Gas Filter and Mixing Chamber.

13. Sample clamps can be used for soft and hard plastics, textiles, fire doors, etc.

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

15. Gas: Nitrogen and oxygen for industrial use, purity > 99%; (User-provided).

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

17. Maximum Usage Power: 50W

18. Igniter: A metal tube nozzle with an inner diameter of 2+1mm at the end can be inserted into the combustion cylinder to ignite the sample. The flame length is 16+4mm and the size can be adjusted.

19. Sample clamp of self-supporting material: It can fix on the axis position of combustion cylinder and clamp the sample vertically.

20. Non-self-supporting material sample clamp: It can fix two vertical edges of the sample on the frame at the same time.

Instrument Structure

1. Control box: NC machine tool is used to process and form, spraying is used to electrostatically spray the steel plate spraying box, and the control part is separately controlled from the test part.

2. Burning cylinder: high temperature resistant and high quality quartz glass tube (inner diameter 75 mm, length 300 mm) outlet inner diameter 40 mm

4. Mixer: Use glass bead filling to mix oxygen and nitrogen evenly. (Pearl 4.5mm filling height 95mm, one bag)

5. Sample fixture: self-supporting fixture, and can clamp the sample vertically; (optional non-self-supporting type of sample holder), two sets of sample holders meet different test requirements; Sample holder plug-in type, placement style and sample holder is simpler.

7. The standard is equipped with glass cylinder to prevent accidental damage and meet the needs of uninterrupted test. The diameter of the tube hole at the tail end of the long-rod igniter is 2+1 mm, and the flame length of the igniter is (5-50) mm, which can be adjusted arbitrarily.

Tips: When testing the oxygen index meter, one bottle of industrial grade oxygen/nitrogen should be used as the gas source. Because the above gas is a high-risk transport product, it cannot be used as the parts of the oxygen index meter. It can only be purchased at the local gas station of the user. (To ensure the purity of the gas, please purchase it at the local regular gas station.)
