Loi-a ASTM D2863 Automatic Lol Limiting Oxygen Index Chamber for Plastics

1. LOI-A ASTM D2863 Automatic LOl Limiting Oxygen Index Chamber is designed to test combustibility by oxygen concentration, letting user know minimum oxygen concentration as necessary for combustion.
   
   The working principle is: Place the specimen into the testing chimney, filling with oxygen and nitrogen into the chimney, burn the specimen, then measure the min concentration of oxygen to support continuous combustion.

   

1. ASTM: ASTM D2863: Standard Test Method for Measuring the Minimum Oxygen Concentration to Support Candle-Like Combustion of Plastics (Oxygen Index).
2. ISO: ISO 4589-2: Determining the minimum volume fraction of oxygen, in admixture with nitrogen, that will support combustion of small vertical test specimens under specified test conditions. The results are defined as oxygen index (OI) values.
3. NES: NES 714.

1. Adopts England original Servomex Paramagnetic type oxygen sensor, which accuracy can be up to +/-0.1%;
2. The sensor is better than traditional electrochemical sensor, because it don't need to change oxygen battery, so, it has long lift time more accurate and faster response time.
3. Equipped with 2pcs Mass Flow Controller(MFC) to control N2 and O2 mixing ratio;
4. Equipped with high temperature quartz glass tank;
5. Equipped with supported and unsupported sample clamps;
6. Equipped with portable ignition device, gas tank connector, accurate pin valve to adjust the flame;
7. Digital setting N2 and O2 concentration;
8. Computer+LABVIEW software to control N2 and O2 mixing ratio, read O2 concentration in mixing chamber, and store&print out test results;
9. Reserve a calibration port to calibrate the sensor;
10. Stainless steel air channel design, equipped with one way fire-resistance valve, magnetic valve, fine filter, so, it is stable and safe;
11. Patented design gas mixing chamber, which ensure the gases can mix the gases in short time, data is more accurate;
12. Resolution: 0.1%
13. Accuracy: +/-0.2%
14. Response time: <300ms
15. Oxygen stability time: <30s

LOI-A ASTM D2863 Automatic LOl Limiting Oxygen Index Chamber can connect with computer.
