Product Description

Introduction:

The high temperature oxygen index tester is designed, developed and manufactured according to ISO 4589-3 (elevated temperature test) and British Naval Engineering standard NES 715.
The high temperature oxygen index measuring instrument is based on the ordinary intelligent oxygen index measuring instrument, and an electric heating device is added at the position of the combustion cylinder to preheat the mixed gas.
The ignition temperature of different materials at a certain oxygen concentration was tested.It is used to determine the combustion performance of self-supporting vertical strip or sheet plastic materials with a thickness of 10.5mm under test conditions. It is also applicable to the combustion performance measurement of vertically supported film or film materials.

Standards:
ISO 4589-3:Plastics - Determination of burning behaviour by oxygen index - Part 3: Elevated-temperature test
NES 715:DETERMINATION OF THE TEMPERATURE INDEX OF SMALL SPECIMENS OF MATERIALS

Technical Parameters:

1. Oxygen concentration measurement range: 0 ~ 100%;
2. Oxygen concentration accuracy: ± 0.1%;
3. Range of nitrogen mass flow controller: 1.0 ~ 15.0l/min; Accuracy 2%;      
4. Range of oxygen mass flow controller: 1.0 ~ 15.0l/min; Accuracy 2%;     
5. Sensor response time: < 2S;   
6. The response time of the whole equipment is less than 10s (the response time of the whole equipment includes the whole process from setting the oxygen concentration, adjusting the flow by the mass flow controller, fully mixing through the mixing barrel, and then discharging from the combustion barrel);
7. Flowmeter range: 1.0 ~ 15.0l/min;  
8. The air flow in the combustion cylinder is 40mm/ s ± 2mm/s, and the concentration adjustment accuracy is ± 0.1%;
9. The air flow at the top of the combustion cylinder is 90mm ± 10mm / S;
10. Portable igniter, 16 ± 4mm downward injection, adjustable;
11. The measurement time is more than 5min, and the accuracy is ± 0.5s;
12. Double flow meter and pressure gauge device: accuracy ± 1%;
13. Working pressure: 0.1MPa;
14. The glass cylinder is 500mm high and 80mm inside diameter.
 

Main features:

1. The Temperature Oxygen Index Tester is equipped with imported paramagnetic oxygen concentration sensor without service life limit (different from electrochemical sensor, the service life is only about 1 year).

2. The High Temperature OI Tester adopts high temperature resistant quartz glass cylinder, with an inner diameter of 40mm at the outlet, an inner cylinder (inner diameter greater than 75mm and height greater than 450mm), an outer cylinder (with a gap of 5mm ~ 10mm between the inner cylinder and the same height as the inner cylinder);    

3. The High Temperature Oxygen Index Instrument is equipped with self-supporting sample holder and non self-supporting sample holder;   

4. The Temperature oxygen index meter adopts nitrogen and oxygen mass flow controllers imported from Japan to accurately control the gas flow with an accuracy of 0.01l/min (different from the float flowmeter, the oxygen and nitrogen flow shall be adjusted manually);

5. The elevated temperature oxygen index test set uses patented gas flow mixing control to accurately control the gas flow;

6. After the oxygen concentration is set on the screen, the PLC LCD touch screen control system automatically adjusts the oxygen concentration according to the set value. Accurate and convenient control;

7. The patented gas mixing chamber ensures more accurate measurement of oxygen concentration and more sufficient mixing of oxygen and nitrogen;

8. The color LCD touch screen displays parameters such as flow, time and experimental results in real time;

9. Double flow meter and pressure gauge device: accuracy ± 1%;

10. The igniter is easy to operate.
 

Control System:

1. PLC with touch screen test has a higher degree of automation;

2. After the oxygen concentration value is set, the system automatically adjusts the oxygen concentration;

3. Key electrical components are imported brands, accurate, reliable and durable;

4. The equipment is equipped with an automatic calibration system to avoid the impact on the test results due to the drift of the oxygen sensor affected by the environment.

5. The one button sensor automatic calibration system is convenient and fast, which avoids the trouble that customers need to equip with standard gas for regular calibration.
 6.The elevated temperature oxygen index test set is equipped with safety protection circuit.
