The Klein Tools IR1 is a handheld infrared thermometer built for tradespeople. It reads surface temperature from -4 to 752°F without contact, using a 10:1 distance-to-spot ratio and a targeting laser. A backlit display, automatic hold and 6.6 ft drop protection suit job sites. It is a rugged point-and-shoot tool rather than a lab instrument, and it competes with general-purpose IR guns on durability and ease of use rather than on advanced features like adjustable emissivity.
