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 25)
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
The following measurement-specific settings must be adjusted to the climatic conditions
before starting measurements. Starting from 10 m distances, the atmospheric influences
of the air must always be taken into account.
