Thermographers continually face the issues presented by reflection and emissivity. Electrical cabinets are full of different materials of varying emissivity ranging from .95 to 0.15 and these values can change with both age and temperature.

The use of infrared target markers helps to standardise the emissivity and gives a non-reflective target therefore reducing issues caused by reflection. Emissivity targets also give a very useful point of reference for the thermographer and as they can be marked with a unique number are excellent references for the technicians who may have to repair the issues found during the infrared survey.
