The main limitation of the Boson 640 is its price, which is significantly higher than consumer-grade models. It is also not a plug-and-play smartphone accessory; it requires a separate power source and display or recording setup. This makes it overkill for simple home inspections. But for professionals who need the highest resolution and widest temperature range, it is a powerful tool.
FLIR C2 Compact Thermal Camera – Best Rugged
The FLIR C2 is a standalone handheld thermal camera built to survive tough environments. It carries an IP67 rating, meaning it is fully protected against dust and can be submerged in up to 1 meter of water for short periods. This makes it suitable for outdoor inspections in rain or dusty job sites. The sensor is an 80 x 60 detector, which is lower resolution than some smartphone models, but the camera compensates with a built-in 2-inch LCD screen that displays thermal and visual images side by side. The temperature range covers -10 degrees Celsius to 400 degrees Celsius.
Real Amazon features for the FLIR C2 are similar to those of the FLIR One Pro, including super resolution technology that upscales the image to 240 x 180 from 80 x 60 for greater detail.
