Measure the radiation intensity (= apparent temperature) from the reflecting source
using the following settings:
Emissivity: 1.0

D
■
You can measure the radiation intensity using one of the following two methods:

Figure 16.3 1 = Reflection source
➲ Please note the following:
Using a thermocouple to measure reflecting temperature is not recommended for
two important reasons:
A thermocouple does not measure radiation intensity
■
A thermocouple requires a very good thermal contact to the surface, usually by
■
gluing and covering the sensor by a thermal isolator.

Method 2: Reflector method
Step
Action
1
Crumble up a large piece of aluminum foil.
2
Uncrumble the aluminum foil and attach it to a piece of cardboard of the same
size.
3
Put the piece of cardboard in front of the object you want to measure. Make sure
that the side with aluminum foil points to the camera.
4
Set the emissivity to 1.0.
