Feature:1. High resolution. Visible light 2 million pixels, 1024 thermal imaging pixels are clearly visible.2. 3 color imaging modes. The instrument provides 3 color palettes:  iron red, rainbowcolor, grey. Choose suitable color palettes to show the details of the target object.3. Two image-fusion functions. Contourline and thermal imaging-fusion display, visible light and thermal imaging-fusion.4. This instrument supports two visual mode switching, which can be compared according to the two measurement diagrams to find the fault point. It is an nice choice for electricians and maintenance technicians and can be used to quickly find the problem area.5. Large capacity imagestorage. Standard 16GB mini memory card with large capacity can store various measurement data.6. USB to read data quickly. The captured pictures saved in the instrument can be viewed and exported by connecting to a computer, which is convenient and quick.Specification:NF-521 has thermal imaging function and can display hot and cold spots on the screen, enabing users to oberve the object temperature changes more effectively. It helpls you to quickly lock the target area. The standard 8GB memory card can save a large number of data, which is a useful tool for fault maintenance.Features:High resolution.
