High Temperature Extreme Oxygen Index Tester - Critical value of oxygen demand concentration during material combustion. High-temperature limit oxygen index tester refers to the volume fraction concentration of oxygen that can support the combustion of materials in a mixture of oxygen and nitrogen gas, and is an index that characterizes the combustion behavior of materials. With the increasing demand for material properties and the wider range of material applications, the testing conditions for the ease of material combustion have become more stringent. The high temperature limit oxygen index tester is mainly used to test the ease of combustion of materials under high temperature conditions, and to control product quality by testing the combustion performance of materials.

Key parts:

1, Imported sensors

Imported high-precision paramagnetic oxygen concentration sensor with high accuracy and stable performance. Real time detection of oxygen concentration, combined with PLC precise control to adjust the oxygen concentration passing through the airflow.

2, Flexible fixture design

The fixture is made of fire-resistant and stainless materials that can withstand high temperatures without rusting, and can hold various samples. By replacing the sample clamp, different characteristics of the sample requirements can be met.

3, 7-inch color screen, intelligent touch, multi-point touch operating system, convenient control, multilingual display, switching between Chinese and English. Simplified operating interface and easy to operate.

4, Quick change structural design

The test tube of the instrument is made of high temperature resistant to transparent glass, and has heating function to improve various high-temperature conditions for the experiment. In addition, the test tube is combined with the base in a quick change design, which allows clear observation of the combustion situation during the test. It is also easy to clean after the experiment. The stainless steel base can avoid various corrosion effects on the test data and has a long service life.

Key Features

1. High temperature limiting oxygen index tester is used to measure the limiting oxygen index of solid materials such as textiles, plastics, laminated materials, foam materials, films and films under various conditions beyond normal temperature, which can be used to evaluate the combustion performance of materials under specified conditions, so as to guide material research and development, provide data basis for product acceptance, and provide data basis for new material research and development, product quality acceptance, etc.

2. The sample is vertically fixed in a transparent heating test cylinder with an upward flowing oxygen and nitrogen mixture gas. The top of the sample is ignited, and the combustion characteristics of the sample are observed. The continuous combustion time or combustion length of the sample is compared with the given limit value. Through a series of experiments at different oxygen concentrations, the minimum oxygen depth value expressed as the percentage of oxygen content during combustion is measured.
