The FLIR TG54-2 enables non-contact temperature measurements. This allows you to take measurements quickly and easily without compromising safety. Thanks to its 20:1 standoff ratio, the TG54-2 can measure smaller targets from a safe distance. With infrared technology, Class II laser targeting, and a maximum IR temperature of 850°C (1562°F), you achieve pinpoint precision. For reliable performance in demanding applications, the thermometer is drop-tested to 3 m and has an IP65 rating.
