Limited Oxyen Index Tester,ASTM D 2863, ISO 4589 FTech-ASTM D2863C
  • Product Introduction

ModelFTech-ASTM D2863C

Introduction

TESTECH Oxyen Index Tester 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 oxygen senser 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.
