Product Features

• Testing Principle: Vertical sample combustion in oxygen/nitrogen gas flow. Combustion time and oxygen percentage are measured to determine LOI.
• Key Components:
  • Heat-Resistant Cylinder: Borosilicate glass (inner dia. >75mm, height >550mm).
  • Stainless Steel Beads: Enhances gas flow uniformity (4mm dia., 80–100mm height).
  • Pilot Burner: 2mm inner dia., 400mm length for precise ignition.
• Gas Control: Automated oxygen/nitrogen mixing with flow rate 12.1L/min.
