Introduction:
This Limited Oxygen Index Tester is suitable for the determination under the test conditions specified in oxygen and nitrogen gas mixture just to maintain a minimum sample combustion oxygen concentration required. This OI analyzer is equipped with an imported paramagnetic oxygen sensor and imported mass flow controller to make sure the measurement accuracy and durability.
The Limited Oxygen Index Tester can be used for the evaluation of the performance of a homogeneous combustion of solid materials, laminates, foams, films and films under specified conditions.

Standard: 
ASTM D 2863,
ISO 4589-2
