R&D Scene
Thermal imaging cameras can indicate material properties under the most demanding conditions and Performing non-contact temperature measurement. A series of infrared sensors type and optical properties make infrared thermal imaging a number of research environments An indispensable part.

Infrared thermal imaging cameras can clearly image small objects, which is of great help to the effect of microscopic imaging. Some similar objects under visible light will show differences in infrared thermal imaging cameras.

Thermal imaging cameras can detect extremely tiny temperature differences, convert the temperature difference into real-time video image display, can see through obstacles such as fog, rain, smoke, etc. It can be used in extreme weather, can be used normally during the day and night for long-distance surveillance or even for homeland security.


Scientists designing and manufacturing circuit boards face the task of managing heat dissipation How to balance the performance or cost of the problem. Accurate understanding of thermal issues Straight is a very difficult thing. However, with thermal imaging, Engineers can easily observe the equipment they manufacture Thermal mode and quantitative analysis to design better products

Medical Field
Infrared thermal imaging technology is outstanding in the medical field, using the infrared radiation energy of the human body itself, and through the photoelectric signal conversion, the infrared radiation information of the human body surface is finally presented in the form of a pseudo-color infrared thermal image. This can help the experts to conduct a more comprehensive diagnosis, and some areas of the disease caused by inflammation, combined with high-precision detectors, can find more subtle symptoms.

HHTI hand-held thermal imager can clearly see people, weapons, and animals in harsh environments such as full black, smoke, dust, rain and snow, trees, camouflage, etc. This has a great effect on finding enemy conditions in advance and quickly finding prey, which can meet fast high-precision stable shooting. Lightweight, small size, easy to carry
