l) Reflected temperature
• Using the offset factor, the low emissivity of the reflection is factored for in the calculation, 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.
• The reflected temperature is only required in the thermal calculation when objects with strong emissions and a
much higher temperature are in the proximity of the object being measured.
• The reflected temperature only has a small effect on objects with a high emissivity.
• The reflected temperature can be set individually.
• Follow these steps to obtain the right value for the reflected temperature:
1 Set the emissivity to 1.0.
2 Adjust the optical lens to near focus.
3 Looking in the opposite direction away from the object, take a measurement and freeze the image.
4 Determine the average value of the image and use that value for your input of the reflected temperature.
m) Thermal imager reporter software
• Thermal imager reporter software is supplied with the thermal imager.
• This software is intended for the thermal imager and contains features to analyse images, organize data and
information, and make professional reports.
• The thermal imager reporter software allows audio annotations and commentary to be reviewed on a PC.
