Product Introduction:
This handheld infrared imager is designed specifically for outdoor use, catering to applications that require mobile inspection and real-time video evidence collection. While delivering high-quality night vision, it emphasizes continuous operational capability in outdoor environments as well as robust image storage and transmission functions. Its compact size ensures the reliable capture of essential inspection images and data.
Product Features:
◆ Fully radiometric thermal imager – records temperature data for every individual pixel; high thermal resolution of 640×480
◆ Extended JPEG recording: files contain full radiometric data while the image itself is saved in a standard format
◆ Live infrared video recording – records video to an SD card or PC; supports live viewing on a PC
◆ Image fusion technology: precise alignment of infrared and visible light images for accurate targeting of the object under inspection
◆ PAL/NTSC video output to external monitors or recording devices; suitable for real-time production process monitoring, etc.
◆ Automatic hot-spot detection and alarms; zoom capabilities for both still images and video; features 8 movable spots, 8 vertical/horizontal line profiles, and isotherms
◆ Intuitive Chinese-language menus and software; easy to operate even for beginners
◆ 5-megapixel visual image recording
◆ 8 selectable color palettes
◆ Built-in Wi-Fi and USB connectivity
◆ Built-in laser pointer and LED flash
◆ 5.7" LCD touchscreen + 0.6" OLED (640×480) viewfinder
◆ Compliant with EN61326-1 standards
◆ Image refresh rate: 50/60Hz; Digital zoom: 4x
