LFY-605A Automatic Rubber/Asphalt Oxygen Index Tester
The main purpose
It is used to determine the combustion performance of various forms of asphalt/rubber, as well as the combustion performance of plastics, paper, etc.
Instrument characteristics
1. Computer control, full Chinese interface, high degree of automation, the operator only needs to input the required oxygen concentration value from the keyboard according to the test requirements, and the instrument can automatically track and adjust to stabilize the oxygen concentration at the set value.
2. Directly detect and display the oxygen concentration value of the sample combustion chamber.
3. The automatic ignition mechanism ensures safe and reliable ignition. After 5 seconds of automatic ignition, move it away to observe whether the sample is ignited and continue to return to ignition. Repeat the previous process until 30s. If it burns, the burning time is automatically recorded.
4. Asphalt special sample holder and rubber special sample holder.
5. The data is processed by the computer and printed out, and the test data can also be displayed directly. And judge the credibility of the obtained test data.
Technical index
1. Flame height: (16±4) mm
2. Detection and display accuracy: oxygen concentration value 10%～60%±0.2LOI
3. The oxygen concentration setting range: 10%～60%±0.2LOI
4. Burning timing: 1s～300s±0.1s
