NF-521S infrared thermal imaging handheld device is a high-precision thermal imaging handheld device. The display method of infrared thermal imaging and visible light can be used to capture the image of each pixel of the target object temperature,and by combining visible light, the state of the object can be photographed more clearly.

Features:
Our thermal image resolution is 120*90 led display ,38°X50° Field of View, 25Hz refresh rate,2.8 TFT LCD Display, clear and smooth video recording.
8 color palettes to choose : Iron Red, White heat, Black heat, Rainbow, Red heat, High contrast, Green heat, Lava,choosing any color palettes according to your work needs.
Automatic tracking of high and low temperature, multi-temperature display and temperature comparison can help you better detect hot spots of electrical devices. The temperature range: -20℃-400℃(-4℉-752℉).
The thermal imager has a built-in 8G memory card, which can be viewed at any time. At the same time, the image can be transmitted to the computer for analysis through the USB cable.
Widely use for wiring and HVAC maintenance, pet search, night vision, anti-candid photography, house water leakage maintenance, etc.
Note:
When in use, do not point the thermal imager at the sun or laser directly, otherwise it will directly damage the machine.
If you want to test the surface of a smooth object, it is recommended to stick electrical tape on the surface of the object first, and the test result will be more accurate.
Optimum test distance is 1 meter (3.2 ft), up to 5 meters (16.4 ft).
