This setting tells the Thermal Imager what surface material it is measuring. This is important, because setting the right emissivity has a significant effect on the accuracy of temperature readings. See Table 5 for a list of the materials in the Thermal Imager Emissivity menu, and their corresponding emissivity ratios. You can also select “CUSTOM” in the emissivity menu, and select any emissivity value. In Figure 11, “CUSTOM” shows “0.30,” but when you select CUSTOM, you can choose any value.

Emissivity is the ratio of a target surface’s infrared output (radiance) to that of a blackbody at the same temperature. A “blackbody” is a theoretical perfect radiator of infrared radiation (IR).

What this means is you can set the sensitivity of the Thermal Imager to determine the true temperature of an object, no matter what its IR radiation characteristics are. The poorest radiators (surfaces with the lowest emissivity ratios) need the most correction. These materials are things like shiny metal and glass.

When you have a low-emissivity surface that you need a very accurate temperature reading from, placing black electrical tape or even painting it with flat-black paint is very effective. Black electrical tape and flat-black painted surfaces have an emissivity ratio of 0.95.

WARNING

To minimize the risk of electric shock, burn or fire, never apply electrical tape or paint to an electrically live surface. Always check to ensure the power has been turned off before touching a surface.
