FAQs

The emissivity of an object is related to its material, surface structure, temperature, etc. Different materials have different emissivities. Usually, the electrically insulated and thermally insulated materials have a higher emissivity; the emissivity of metals is relatively low. Surface polishing reduces emissivity while frosting increases emissivity. For example, polished metals such as aluminum have a low emissivity of about 0.1, while materials such as wood or fabric have a higher emissivity of about 0.9. The emissivity of human skin is about 0.98, so people can emit infrared radiation very effectively, allowing the infrared thermal imaging camera to accurately capture body temperature and heat signals.

The emissivity is the ability of different objects to emit infrared radiation. It is a key factor affecting the thermography accuracy of infrared thermal imaging cameras. It is a coefficient between 0 and 1. The larger the value, the higher the emissivity and the stronger the infrared radiation capability.A black body is an ideal object with an emissivity of 1, which only emits radiation and has no reflection.

01 Thermography

Non-contact long-distance thermography and fault detection can be realized:

1. Simple and intuitive; 2. safe and accurate; 3. efficient and time-saving; 4. all-weather work

▲ Power monitoring

02 Night Vision

Targets can be easily detected and identified in the absence of light:

1. All-weather operation; 2. no fear of bad weather; 3. long working distance; 4. super strong concealment

Thermography and all-weather imaging are the two basic functions of infrared thermal imaging technology.

In addition to being used in traditional fields such as military, electricity, industrial manufacturing, scientific research, and medical care, the products developed based on these two are about to enter our daily lives with a new attitude.

In layman's terms, infrared thermal imaging is a technology that turns invisible infrared radiation into visible thermal image and can reflect the temperature distribution state of the target surface. Different objects and even different parts of the same object have different radiation capabilities and their reflection strength to infrared rays. Using the difference in radiation between objects and the background environment, as well as the differences in radiation from various parts of the scene itself, infrared thermal images can show the radiation fluctuations of various parts of the scene, thereby showing the characteristics of the scene.

Any object with a temperature above absolute zero (-273°C) will radiate infrared rays that are invisible to the naked eye, also known as thermal radiation. With the infrared thermal imaging technology, thermal radiation is converted into corresponding electrical signals, which are then amplified and processed to obtain a thermal image reflecting the thermal distribution on the surface of an object.
