Description

The instrument creates a controlled gaseous atmosphere in which a sample can be ignited. By being able to control the concentration of oxygen in the environment, it is able to determine where on the combustible curve the material will continue to combust. As such, the LOI tester is widely used for quality assurance, research, and regulatory compliance testing in many industries, such as plastics, packaging, automotive, electrical, and textile. 

The LOI tester was designed in accordance with internationally recognized testing methodologies such as ASTM D2863 and IS 13360 (Part 6/Section 19), so that test results can be accepted and used with high accuracy internationally.
