TLOI Minimum Oxygen Concentration Tester

Introduction:
TLOI Minimum Oxygen Concentration 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 tester equipped with imported mass flow controller to make sure the measurement accuracy and durability. For the assessment of the performance of a homogeneous combustion of solid materials, laminates, foams, films and films under specified conditions..
