[QUOTE="A/C Guy, post: 1943409, member: 13490"] I am an HVAC contractor and use IR thermometers daily. They do not work on copper, nor do they work on brass. Google is your friend: What is the role of emissivity in infrared thermometers? The Role of Emissivity in Infrared Thermometers. Infrared thermometers measure surface temperatures of objects by sensing the infrared radiation emitted by the object’s surface. Afterward, they make a direct correlation between the amount of radiant energy being detected and the surface temperature of that object. [URL='https://ennologic.com/emissivity-infrared-thermometer-readings/']Emissivity and Its Effect on Infrared Thermometer Readings ...[/URL] ennologic.com/emissivity-infrared-thermometer-readings/ Small changes in an object’s emissivity can result in noticeable affects on measured temperature. A 0.02 reduction in emissivity, for example, can decrease the measured temperature of an object at 100°C by approximately 2°C. Likewise, variations in the ambient temperature can affect measured temperature.
