WJHC-5 intelligent automatic touch screen control oxygen index measuring instrument

First, WJHC-5 intelligent automatic touch screen control oxygen index analyzer product advantage:

1. Full-color touch screen control, just set the oxygen concentration on the touch screen, the program will automatically adjust to the oxygen concentration balance and issue a sound prompt, eliminating the trouble of manual adjustment of oxygen concentration;

2. The Stepping Proportional Valve greatly improves the control precision of the flow rate. The closed-loop control is adopted. The oxygen concentration drift program is automatically adjusted back to the target value in the test, which avoids the drawback that the traditional oxygen index meter can not adjust the oxygen concentration in the test and greatly improves the test precision.

Two, WJHC-5 intelligent automatic touch screen control oxygen index instrument main technical parameters

1. Using imported oxygen sensor, the digital display of oxygen concentration need not be calculated, the accuracy is higher and more accurate, the range is 0-100%.

2. digital resolution: + 0.1%

3. measurement accuracy: level 0.1.

4. touch screen setup program automatically adjusts oxygen concentration.

5. one button calibration accuracy

6. one click concentration

7. stable oxygen concentration automatically prompting alarm.

8. with timing function

9. can store experimental data.

10. you can query historical data.

11., clear historical data.

12. you can choose whether to burn 50mm.

13. gas source fault indication

14. oxygen sensor fault indication

15. oxygen nitrogen fault indication

16. oxygen sensor aging tips

17. standard oxygen concentration input

18. the diameter of the combustion chamber can be set (two commonly used specifications are optional).

19. flow regulation range: 0-20L/min (0-1200L/h)

20. quartz glass canister: one of the two specifications is optional, with an inner diameter of 75 or more than 85 mm inside diameter.

21. gas flow rate in combustion chamber: 40mm + 2mm/s

22. the overall size of the machine is 650mm * 400 * 830mm

23. pressure gauge accuracy 2.5, resolution: 0.01MPa

24. test environment: ambient temperature: room temperature to 40 degrees centigrade; relative humidity: less than 70%;

25. input pressure: 0.25-0.3MPa

26. working pressure: nitrogen 0.15-0.20Mpa oxygen 0.15-0.20Mpa

27. the sample clip can be used for soft and hard plastics, all kinds of building materials, textiles, fire doors, etc.

28. Propane (butane) ignition system, the ignition nozzle is made of a metal tube, the tail has a diameter of 2 (+ 1 mm) nozzle, free bending. It can be inserted into the combustion tube to ignite the sample. The flame length is 16 + 4mm, and the size 5mm-60mm can be adjusted freely.

29. Gas: nitrogen and oxygen for industrial use, purity > 99%; (user-owned/regular gas station industrial oxygen purity is generally 99.2% - 99.3%).

30. power requirements: AC220 (+10%) V, 50HZ

31. maximum power usage: 150W

32. self supporting material sample clip: it can be fixed on the axis of the combustion tube and can clamp the sample vertically.

33. Non-self-supporting material clamp: can fix two vertical edges of the specimen on the frame at the same time (select/apply to soft non-self-supporting materials such as textiles)

Three, design standard: GB/T 2406.2-2009

Tips: Each bottle of industrial grade oxygen/nitrogen not less than 98% should be used as the gas source for the test of the Oxygen Index Detector. Because the above gases are high-risk transport goods, they can not be supplied as accessories for the Oxygen Index Detector, and 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).
