Applications:

The limit oxygen index tester is used to measure the limit oxygen index of solid materials such as textiles, plastics, laminated materials, foam materials, film and film. It can be used to evaluate the combustion performance of materials under specified conditions, thus guiding material research and development and providing data basis for product acceptance.
 

Product Information:

The limit oxygen index refers to the concentration of oxygen in the oxygen and nitrogen mixture when it has just been able to support its combustion. The index is an index of the burning behavior of the material. The limit oxygen index tester can be used to test the material's limit oxygen index (LOI) to determine the degree of difficulty in the combustion of the material, and control the quality of the product through the combustion performance of the test material.
 
Features:
◆ Using paramagnetic oxygen concentration meter, the minimum oxygen concentration of the combustion is accurately detected. No manual calculation is required. Meanwhile, it has good traceability and accurate and reliable.
◆ Oxygen, nitrogen content manual coarse adjustment combined with closed-loop automatic fine tuning section mixing gas concentration ratio, quick and accurate.
◆ 7-inch full-color touch screen, human interface design, simple operation, and other upper computer test software, provide data storage printing function.
