6.12-Reflected Temperature
6.13-Thermal Imager Reporter Software
Using the offset factor, the reflection is calculated out due to the low emissivity and the accuracy of the
temperature measurement with infrared instruments is improved. In most cases, the reflected temperature
is identical to the ambient air temperature. Only when objects with strong emissions with much higher
temperature are in the proximity of the object being measured should be determined and used. The reflected
temperature has only little effect on objects with high emissivity. The reflected temperature can be set individually.
Follow these steps to get the right value for the reflected temperature.
Set the emissivity to 1.0
Adjust the optical lens to near focus
Looking in the opposite direction away from the object, take a measurement and freeze the image
Determine the average value of the image and use that value for your input of reflected temperature.
Thermal Imager Reporter software is supplied with the Thermal Imager. This Software is intended for
Thermal Imager and contains feature to analyze images, organize data and information, and make professional
reports. Thermal Imager Reporter software allows audio annotations and commentary to be reviewed on a PC.
