High Precision Digital Oxygen Index Test Apparatus ISO 4589 ASTM D2863

Application:

Under predetermined conditions, in a mixed stream of oxygen and nitrogen measured, just to maintain the minimum oxygen concentration of the sample required for combustion (also known as the oxygen index) - expressed in percent by volume. It can be used to determine the combustion performance of a variety of textiles, including woven, knitted and non-woven fabrics, etc. Also be used to determine the burning of the plastics, rubber, paper, etc

Standards:

ISO 4589-2 Plastics; Determination of flammability by oxygen index--Part 2:Ambient-temperature test

NES 714, NB/SH/T 0815, TB/T 2919, IEC 61144, GB/T 2406, GB/T 5454, GB/T 10707, GB/T 8924, GB/T 16581, ASTM D2863, ISO 4589-2

Features:

1. The Limiting Oxygen Index Tester 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;
