The Limiting Oxygen Index (LOI) fire test is perhaps the most economical and precise quality control test for combustible materials. Its ease of use together with high levels of precision has made this technique a primary characterization and quality control tool for the plastic materials and electric cable industries. It is often used in materials specifications and material/product data sheets . The test assesses the minimum percentage of oxygen in the test atmosphere that is required to marginally support combustion.

The unit has been designed to be compact for efficient use in a standard fume cupboard (or under a simple ventilation hood that we can also supply if required). The unit gives continuous digital readout of oxygen concentrations in the test atmosphere to facilitate quick settings of test concentration. Stabilised oxygen percentages are read from the digital readout and no additional flow adjustments are required. This is a considerable improvement over systems that use analogue gauges or require flow matching and the use of graphs or tables to calculate oxygen concentrations. This makes the unit as automatic as is feasible.

While many designs of the LOI test apparatus calculate oxygen index based on the flow of oxygen and nitrogen, the unit incorporates a paramagnetic oxygen analyzer for precise measurement of oxygen concentration without the need for calculations and frequent recalibrations.
