Advanced Thermal Imaging Technology and Versatile Display Modes

This handheld thermal imager features an impressive 3.2-inch display with multiple image display modes including infrared, fused, visible light, and dual light fusion options. The thermal imaging camera supports five color palettes—rainbow, iron red, cold color, black & white, and white & black—enabling users to select the most effective visualization for their specific inspection needs. The wide temperature measurement range of -20°C to +550°C (-4°F to 1022°F) covers virtually all applications, from detecting energy loss in buildings to monitoring high-temperature industrial processes. Temperature measurement accuracy of ±2°C or ±2% ensures reliable data collection, while the 0.1°C resolution provides detailed temperature analysis. The center point measurement and hot/cold spot tracking features automatically identify critical temperature extremes, saving valuable inspection time. With adjustable emissivity from 0.01 to 1.00, the D-18+ can accurately measure temperatures on various surface materials, from reflective metals to matte finishes. The ≤25Hz frame rate delivers smooth thermal imaging, ensuring no detail is missed during dynamic inspections. Built-in 4G eMMC storage provides approximately 3GB of space for capturing and storing thousands of thermal images and videos in standard JPG and MP4 formats.
