Reflection temperature
Infrared measurements of specific objects can be affected by reflection from other objects nearby or even
from the ambient air because the measured object cannot be fully isolated. The reflection temperature
setting can help compensate for the interference. The reflection temperature is generally the same as the
ambient temperature. However, if larger objects with significantly different temperatures (approx. > 20 °C)
are in close proximity to the measured area, its effects must be taken into account. For this purpose,
follow these steps:
1. Set emissivity coefficient to 1.0
2. Blur the object out of focus (Refer to Section 14)
3. Aim the camera in the opposite direction of the actual measured object
4. Determine the average temperature
5. Set the average temperature as the reflection temperature
