ISO 4589-2 ASTM D 2863 NES 714 Intelligent LOI Limited Oxygen Index Tester
Limited Oxygen Index Tester Introduction:
The Limited Oxygen Index Tester is designed to determine the
minimum oxygen concentration required to sustain combustion of
materials under controlled conditions. Utilizing an imported
paramagnetic oxygen sensor and high-precision mass flow
controllers, this analyzer ensures accurate and reliable results
for homogeneous solids, laminated materials, foams, films, and
textiles. It is ideal for laboratories and industries focused on
fire safety evaluation, compliant with ISO 4589-2, GB/T 2406-2009,
and other international standards.
