COI Paramagnetic ISO4589-2 Plastic Limiting Oxygen Test Apparatus

Introduction:

COI Paramagnetic Type Limited Oxygen Index Apparatus is a convenient device to measure minimum oxygen concentration during combustion of specimen.

COI Limited Oxygen Index Apparatus adapts Paramagnetic Type oxygen sensor which has a precise, long life, less error rate and high reliability.

Reference Standards:

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.

Parameters:

Features:

1. Paramagnetic Oxygen Cell for assessing accurate oxygen (< 0.1%) levels.
2. Digital display of nitrogen gas flow, total flow ofoxygen and nitrogen.
3. Digital display of oxygen percentage in atmosphere during test (no calculations needed).
4. High temperature resistant quartz glass tube, can withstand a higher test temperature.
5. Gas ignition device, easily adjust the length of the flame.
6. Sample holders for both rigid and flexible samples supplied.
7. Shortened gas path for rapid response.
8. Paramagnetic Oxygen Sensor: Range:0 to 100%
9. Oxygen. Repeatability (typical): ±0.1% Oxygen.
