Thermal imager is mainly composed of infrared optical system (silicon, germanium, zinc and other materials), infrared focal level detector, processing circuit, display and so on.

Thermal imaging allows us to see another radiation world that the human eye cannot see, and can obtain a lot of information that is very important for production and scientific research.

Chemistry is a science that studies the nature, composition, structure and the law of change of matter at the level of molecules and atoms. The object of study is matter, and the content of study includes composition, structure, property, change and use.

Chemical research is of great significance: chemical research can help human beings make better use of natural resources, help human beings open up new roads in energy, materials and other fields, and help people understand nature and transform nature. University laboratories take chemistry research as a key discipline, and research institutes and testing centers also take chemistry as a key observation project.

The chemical reaction is generally in the form of heat energy exchange with the external environment, through the heat change can be obtained chemical reagent reaction degree, different reagent ratio, concentration, and heating temperature will affect the degree of chemical reaction, therefore, the study of chemical reaction energy change, mainly focused on the heat problem.

In the application of studying chemical reactions, accuracy, reliability, sensitivity and high performance are crucial. The main functions and roles of infrared thermal imager in chemical research reactions are:

1. Chemical reagent reaction temperature change monitoring

2. Real-time temperature curve report can be exported online

3. Support image or video secondary analysis

4. Support 24/7 monitoring requirements

Field test: In the process of reaction between benzene and concentrated sulfuric acid, the ratio of benzene and concentrated sulfuric acid of different doses is generated, and different reaction phenomena will occur. The reaction heat is affected not only by the concentration of sulfuric acid, but also by the reaction temperature. The degree of reaction at different temperatures gives off different amounts of heat. The reaction state of the reagent can be obtained intuitively by observing the temperature change, which provides an important theoretical data basis for chemical research.

This test is a rapid reaction and the reaction time is short. For longer chemical reactions, infrared thermal imaging can be used for long-term uninterrupted monitoring, reducing the pressure on researchers.
