NF-521S Infrared Thermal Imaging Handheld Device NF-521S Infrared Thermal Imaging Handheld Device The NF-521S is a high-precision thermal imaging handheld device, perfect for capturing clear images by integrating infrared thermal imaging with visible light technology. This allows you to photograph the state of the object more clearly by examining each pixel's temperature. Features: High thermal image resolution of 120x90 with a 38°x50° field of view. Smooth 25Hz refresh rate on a 2.8" TFT LCD display. Eight color palettes available: Iron Red, White Heat, Black Heat, Rainbow, Red Heat, High Contrast, Green Heat, and Lava, enabling customization to suit your work needs. Automatic tracking of high and low temperatures, with multi-temperature display and comparison to efficiently detect hotspots in electrical devices. Temperature range: -20℃ to 400℃ (-4℉ to 752℉). Built-in 8G memory for anytime viewing, and the capability to transfer images to a computer via USB for detailed analysis. Versatile applications including wiring and HVAC maintenance, pet search, night vision, anti-surveillance, and home water leakage maintenance. Note: Do not point the thermal imager directly at the sun or laser as it may cause damage. For accurate surface temperature readings on smooth objects, apply electrical tape before measurement. Optimal test distance is between 1 meter (3.2 ft) and up to 5 meters (16.4 ft).
