The Milwaukee 2278-20 is a bare-tool infrared thermometer that runs on the M12 battery platform. It reads surface temperatures from -22°F to 1022°F with a 12:1 distance-to-spot ratio, so it measures a 1 ft spot from 12 ft away. A high/low alert and a shielded LCD aim to make scanning fast indoors and outdoors, and the reinforced frame, bumpered nose and 6 ft drop rating suit job-site use. It suits tradespeople already on M12 who want a rugged temp gun; buyers without M12 batteries must add a battery and charger.

Owners rate it highly, praising the clear screen, fast scanning and rugged build. The main complaint is that it ships without a battery.
The Milwaukee 2278-20 is an M12 infrared temperature gun that measures surface temperatures from -22°F to 1022°F. It has a 12:1 distance-to-spot ratio, so it reads a 1 ft. spot from 12 ft. away. This is the bare tool, and the M12 battery is not included.
The LCD screen is built for clear reading indoors and outdoors. Hold, Max, Min, Avg and Diff modes are available. A High/Low temperature alert can be set by the user, and the buttons are labeled for easy setup.
A 7-point reinforced frame, a fully bumpered nose and a shielded LCD let it survive 6 ft. drops. The grip is overmolded for easy handling.
