NF-B522 Handheld Infrared Thermal Imager 96×96 Sensor -20 C to 550 C

The NF-B522 Infrared Thermal Imager is a professional-grade handheld thermal camera designed for fast and accurate temperature diagnostics across electrical, HVAC, plumbing, automotive, and building inspection applications. Equipped with a 96×96 infrared sensor, this device captures clear thermal images to reveal hotspots and cold spots that are often invisible to the naked eye, enabling quick troubleshooting and preventive maintenance.

The NF-B522 features a 2.8-inch color display with multiple palette options, including iron red, white heat, black heat, rainbow, red heat, high contrast, green heat, and lava. Adjustable emissivity settings allow accurate temperature measurement across different materials. Its ergonomic, rugged design ensures comfortable use in field conditions, while a laser spot measurement function improves precision when identifying target areas.

With full support for point, area, and max/min temperature measurement modes, this thermal imager provides versatile inspection capabilities. Users can quickly capture still images or short video clips, store them internally on the 8GB memory, and transfer data via USB Type-C. The 2600 mAh rechargeable battery offers up to 4 hours of operation, making it suitable for extended field use.
