LFY-605A Automatic Rubber/Asphalt Oxygen Index Tester

Main application
It is used to measure the combustion performance of various forms of asphalt/rubber, and is also applicable for the combustion performance measurement of plastics, paper, etc.
Instrument features
1. It is controlled by a computer, with a full Chinese interface. The automation level is high. 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 keep the oxygen concentration stable at the set value.
2. It directly detects and displays the oxygen concentration value in the sample combustion chamber.
3. The automatic ignition mechanism ensures safe and reliable ignition. After 5 seconds of automatic ignition, it moves away to observe whether the sample is ignited, and then returns to ignite again. Repeat the previous process until 30 seconds. If there is combustion, the combustion time will be automatically recorded. 
4. Special sample holders for asphalt and special sample holders for rubber.
5. The data is processed by the computer, printed out, or displayed directly. The reliability of the obtained test data is also evaluated.

Technical indicators
1. Flame height: (16 ± 4) mm 
2. Detection accuracy: Oxygen concentration value: 10% - 60% ± 0.2LOI
3. Oxygen concentration setting range: 10% - 60% ± 0.2LOI
4. Combustion timing: 1s - 300s ± 0.1s
