Instructions for use
Things to consider when measuring temperature with the thermal imaging camera
• The most common application for a thermal imaging camera is to use it to see
the hot and cold areas and temperature differences around a window, in a wall cavity
or radiator for example. The colours on the display show hot (red) and cold (blue)
areas (if the colour palette of the camera has been set to red/blue). The different
colours make it easier to see the areas on the camera display having different
temperatures and this is usually more important than the actual temperatures.
• The colours on the image only show which part of area is cold and which part is hot.
The blue area in one heat map image need not necessarily have the same
temperature as a blue area in another heat map image. The blue colour only
shows which part of the image is colder compared to the rest of the image.
If you would like to
measure
the temperature, there are some things you need to consider:
• In simple terms, you could say that the thermal imaging camera registers
the infrared (IR) radiation an object emits.
• Temperature measurement depends on the emission factor of the object. The emission
factor is a measure of the capacity of a material (object) to emit infrared radiation.
• The emission factor differs between materials and is influenced by surface colour
and texture.
• In order to achieve more accurate temperature measurements, it is therefore
necessary to set the emission factor of the camera to suit the material and surface
texture of the object being measured.
• The camera menu has a function for setting the emission factor. The camera has
4 set values: 0.95, 0.80, 0.60, 0.30 and a menu where you can select your own
emission factor from 0.10 to 1.00.
