Infrared Thermometers Introduction The 566 and 568 Infrared Thermometers (“the thermometers”) are for non- contact temperature measurement. These thermometers determine an object’s surface temperature by measuring the amount of infrared energy radiated by the object’s surface. The thermometers also support contact-temperature measurement via K-type thermocouple. Note that the Japanese models indicate Celsius only. Contacting Fluke To contact Fluke, call one of the following telephone n
