Safety Precautions
The infrared thermometer measures temperature by infrared radiation (heat rays) discharged from the material being measured. The discharge of infrared radiation is referred to as emissivity. Factory default emission setting is 0.95 which is typical. However, a shiny or glossy surface of the material being measured will impact on the reading of the temperature as the emissivity is deceptively lower. For this purpose, factory settings are adjustable.

Low temperature High temperature
High temperature generally discharges higher infrared radiation than a low temperature.

Emissivity = 0.2 Emissivity = 0.95
Emissivity becomes lower in glossy or shiny materials with the same temperature.
