The screen size selection of an infrared detector mainly depends on multiple factors such as its usage scenario, portability requirements, and budget. Generally speaking, for handheld infrared detectors, the screen size should not be too large to ensure the portability and ease of operation of the device. For fixed or vehicle mounted infrared detectors, the screen size can be selected based on actual needs and observation distance.

  Common infrared detectors on the market have screen sizes of 2.8 inches, 3.5 inches, etc., which usually provide sufficient display area to clearly display infrared images. However, the specific screen size still needs to be determined based on the specific model and function of the infrared detector.

  Additionally, it should be noted that screen size is not the only factor to consider when choosing an infrared detector. It is also necessary to pay attention to the performance indicators of the infrared detector, such as resolution, temperature measurement range, detection distance, and reaction speed, to ensure that the selected equipment can meet practical usage needs.

  Therefore, when selecting the screen size suitable for infrared detectors, it is recommended to conduct a comprehensive evaluation based on specific usage scenarios and requirements, combined with the performance parameters of the product. If conditions permit, you can consider trying different screen sizes in actual usage environments to choose the most suitable product for yourself.
