Critical (Limiting) Oxygen Index Test Apparatus

This well-established test complies with a very wide range of national and international standards. It is widely used as a laboratory research tool to measure the comparative FR properties of different materials.

Available Models:

• OI-1
• OI-1-X (export)

Features:

• Utilizing the latest oxygen analyzer technology, the unit provides a stable, digital readout of oxygen concentration to ± 0.1%.
• A heavy duty Pyrex chimney is provided, along with two types of sample holder:
  1. For non-self-supporting sheet samples (e.g. textiles, films, papers, etc.). Sample size: 150 x 37.5 mm and up to 12 mm thick.
  2. Self-supporting rod samples (e.g. plastics, wood, etc.). Sample size: 150 mm length and up to 10 mm diameter.
• Automatic calibration.
• Digital selection of oxygen concentration by push-button control.
• Adjustment of oxygen and nitrogen flow is automatic to achieve the desired oxygen concentration.
• Digital Display: Instrument status, oxygen concentration, flow rate, chimney temperature, elapsed time.
• All necessary control valves, flowmeters and filters are built in and the instrument is easy to use.
• The apparatus is supplied complete with a burner assembly and instruction manual.
• 110 V 50/60Hz or 230 V 50Hz
