Review:
Demonstration Thermography Report to highlight the capabilities of the Testo 875 series Thermal Imaging
camera and the Testo IR software.
This is an example report for Demonstration purposes only. The report format is using the "Standard" report
template from the selection of Report Templates available in the Testo IR software.
A demonstration of the Testo 875-2 Thermal Imaging camera was conducted for a Heating / Power Fluching
Contractor, during the course of Power Flushing being conducted at Dwelling.
The objective was to demonstrate how a Testo 875-2 Thermal Imaging camera could be used to record
Thermal and Digital images during the course of the Power Flushing process, to show the conditions of the
radiators prior to and after the process and to verify the the improvements made, using Power Flushing
.
The Boiler was switched on just prior to arrival and images were subsequently captured of the radiators, to
record their condition / performance.
With reference to the images at this stage, a number of the radiators had significant cold areas, indicating
substantial contaminant / sludge and the need for Power Flushing.
Images of the Lounge, Hall, Bedroom 1 and Bedroom 2 Radiators, (which were the radiators in the worst
condition), were recorded for the purpose of comparison, following the process.
Images were also recorded during the Power Flushing process and specifically the images 0839, 0840 & 0845
show the Lounge radiator changing / improving condition during the process.
Following completion of the Power Flushing process on all the radiators, the boiler was switched on and the
heating system was operational and images of the Lounge, Hall, Bedroom 1 and Bedroom 2 radiators were
recorded for comparison purposes and to highlight the significant improvements in Condition / Performance.
As can be seen, the thermal images clearly show the conditions of the radiators before, during and after the
Power Flushing process and verify the improvements that this process produces.
The purpose of the report is to demonstrate the capabilities of the Testo 875-2, a 160 x 120 pixel configuration
Thermal Imaging camera in respect of the image quality / resolution that is recorded/produced with this level of
Thermal Imaging camera and to demonstrate how it can be used to verify the Power Flushing process.
Please note that any temperatures indicated on the images are "Apparent Temperatures" and may not be
truely representative. An overall emissivity value has been used in the images for these demonstration
purposes. For accurate temperature measurement, the relevant emissivity value to the specific material to be
measured, would have to be established.
It should be noted that Testo do not provide a Thermography Consultancy Service, the images are purely for
Equipment Demonstration purposes to highlight the capabilities of the Testo range of Thermal Imaging
cameras and the Testo IR software.
It is not the purpose of the images/report to specifically identify/highlight any faults or Thermal Anomalies, or to
provide comment/observation relating to any anomalies.
Some of the features of the camera and software have also been applied to the Thermal images.
Spot Temperature markers have been added to the thermal images to indicate temperatures.
Auto Hot / Cold Spot Indicator has been applied, which automatically highlights the Hottest or Coldest point
in the defined area.
Temperature Profile Line Graph shows the temperature variation in graph form across the subject.
Palettes a variety of palettes have been used for the thermal images. Eight palettes are available on the
camera and in the software.

The images are automatically Time and Date Stamped to verify the time and date when the images were
taken.
The report also details the Emissivity value relating to the image taken.
