2. What are the technical indicators of the electronic thermal imager

Electronic thermal imaging cameras have a wide range of uses. When choosing, pay attention to selecting infrared thermal imaging camera products with appropriate technical indicators according to your needs:

1. Thermal sensitivity

It refers to the ability of an electronic thermal imager to distinguish small temperature differences. It affects the fineness of imaging to a certain extent. The higher the sensitivity, the better the imaging effect.

2. Infrared resolution

That is, the detector pixels of the thermal imager are similar to visible light. The higher the pixel, the clearer and more delicate the picture, and the higher the pixel, the more temperature data can be obtained at the same time.

3. Temperature measurement range

Refers to the range from the lowest temperature to the highest temperature that the electronic thermal imager can measure. There are multiple temperature ranges within the range, which can be set manually. Select the appropriate range according to the temperature measurement target, and the thermal image will be clearer.

4. Full radiometric video streaming

Save the video stream of the temperature data of each pixel of each frame, the full radiation video can be used for post-temperature change analysis, and can also perform arbitrary temperature analysis on each frame of pictures.
