High Temperature Oxygen Index Testing Equipment , Oxygen Index Chamber

ISO 4589-3 High Temperature Oxygen Index Testing Equipment AC 220V 50/60Hz 2A

Introduction:

This Oxygen Index Tester is used to determine the lowest oxygen density that tested materials keep steady burning under oxygen and nitrogen mixed gas. (expressed as a percentage).The oxygen index is an important reference value to measure the flame retardant properties of materials. This tester is imported paramagnetic oxygen concentration sensor, accurate measurement, long life, low error rate, high reliability.

Parameter

Type:YY907

Size:600(W)×310(D)×545(H)mm

Power: AC 220V 50/60Hz 2A

Weight: About 30KG

Need to prepare air: Oxygen and nitrogen

Features:

1. Equipped with paramagnetic oxygen concentration sensor, the display oxygen concentration accuracy is 0.1%, compared with the traditional electrochemical oxygen sensor, there is no service life limit (electrochemical oxygen sensor requires frequent replacement of oxygen battery), higher precision, faster response time

2. Equipped with 2 mass flow controllers (MFC) to control the mixture ratio of nitrogen and oxygen, accurate and convenient control

3. Automatic closed epoxy concentration control, precise control of oxygen concentration in the combustion chamber

4. Mixed gas temperature can be controlled to 400 ℃

5. The ring heater can efficiently preheat the mixed gas

6. The temperature column may be used to observe specimen and may also emit high temperature radiation

7. The temperature controller can adjust the temperature of the preheater and the temperature column

8. Equipped with air pump to prevent safety accidents before oxygen and nitrogen filling to ensure smooth combustion testing

9. Equipped with high temperature resistant quartz glass cylinder

10. Equipped with supporting and unsupported sample jig

11. Portable igniter with quick connection of gas tank and precise needle valve to adjust flame size

12. PLC+ touch screen control, digital set nitrogen, oxygen concentration, without repeated manual adjustment

13. Desktop computer + professional control software, to achieve the guidance of the entire test process, and store the output

Standards:

ASTM D 2863, ISO 4589-3, NES 715, GB/T 2406.2
