DRK-60D 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. Temperature Control with Temperature Controller

3. Digital Resolution：±0.1%

4. Measurement accuracy: 0.4 level

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

6. Response time: <5S

7. Burning cylinder: inner diameter (> 75) 400 mm high

8. Gas flow rate in combustion cylinder: 40 mm (+10 mm/s)

9. Pressure gauge accuracy 2.5, resolution: 0.01MPa

10. Flow meter: 1-15L/min (60-900L/H) adjustable, test environment: ambient temperature: room temperature-40;, relative humidity: <70%;

11. Input pressure: 0.2-0.3 MPa

12. Working Pressure: Nitrogen 0.1-0.15Mpa Oxygen 0.1-0.15Mpa 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: CNC machine tools are used for processing and forming, electrostatic spraying, beautiful, rust-proof and anticorrosive. The control part is separated 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.
