Nowadays, due to the impact of the global epidemic, people pay more and more attention to outdoor activities. At the same time, people's outdoor activities are becoming more and more colorful, no longer limited to outdoor outings and hiking. With the popularity of domestic infrared thermal imagers, people are becoming more and more interested in infrared thermal imaging. However, there are a lot of thermal imaging products on the market, and many people do not understand infrared thermal imaging, so they are easily fooled. Here are some things you should pay attention to when purchasing infrared thermal imaging.

Infrared thermal imaging pixels:

Before buying an infrared thermal imager, pay attention to the pixels of the detector. Most infrared thermal imaging levels are related to pixels. This is a more important parameter for choosing an infrared thermal imager, which will directly affect the final imaging effect. Generally speaking, the higher the pixel of the detector, the clearer the image and the better the experience. Common detector pixels are: 160*120, 384*288, and 640*512, but the higher the pixel, the higher the price.

Display resolution:

In addition to the detector pixels just mentioned, the resolution of the display is also one of the important factors that determine whether the image is clear. When the detector pixels of the thermal imager are consistent, the higher the resolution of the display, the clearer the image. Common display resolutions are: 1280*720, 960*540, 800*600, 640*480, because the resolution of the display will directly affect the clarity of the image.

Field of view and spatial resolution:

The spatial resolution of an infrared thermal imager refers to the smallest area that the infrared thermal imager can identify. The smaller the spatial resolution, the more accurate the detected temperature, the richer the information contained in the infrared thermal image, and the clearer the image.

Protection level: When observing outdoors or walking at night, it is always on the mountain, so it is necessary to ensure that the infrared thermal imager has a certain degree of anti-fall ability and a certain degree of waterproof and dustproof ability.
