The LOI Limiting Oxygen Indexer enables quality control and determines the relative flammability of plastics compounds by calculating the minimum oxygen concentration that will support combustion.
Features: flexible sample testing - specimens may be in rod, film or composite form; uniform combustion atmosphere - nitrogen and oxygen are fully mixed in a dispersion chamber and glass bead bed before entering column; ISO 4589-1, ISO 4589-2 and ASTM D2863 compliant; precision flow metering - micro-adjustment flowmeters allow precise control of gases; accurate calculation of oxygen concentration; rigid specimen holder; uniform combustion atmosphere; dual inlet gas pressure gauges (0 to 100psi); chimney gas dispersion chamber with glass bead bed; ignition wand with variable gas control valve; gas line inlet filters; smoke density measurement system (optional) - records variations in smoke generation throughout test (120V AC or 230V 50Hz); U-shaped holder for non-rigid specimens (optional).
