Technical highlights of the testo 865 thermal imager
The testo 865 thermal imager stands out thanks to its easy operation and has the following impressive technical features:
- Very good image quality due to high resolution: 19,200 temperature measuring points ensure precise thermography. Infrared resolution of 160 x 120 pixels – via integrated SuperResolution Technology 320 x 240 pixels
-
- Visualize temperature differences from 0.12°C
-
- Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
-
- The IFOV warner means the distance from the measurement object / measurement spot size is determined and the measurement spot is shown on the thermal image – you therefore avoid measurement errors because the camera shows you exactly what you can measure
-
- Pro software for image evaluation on the PC
-
- You can choose to save thermal images as JPEGs

Applications
Detecting structural defects and ensuring construction quality (especially: air tightness of windows and doors)
Analysis with a Testo thermal imager is a fast and efficient method of detecting possible structural defects. Furthermore, Testo thermal imagers are ideally suited for providing proof of the quality and correct implementation of construction measures. Any heat losses, humidity and lack of air tightness in a building are visible in the thermal image. The Testo thermal imager makes it possible to detect faulty thermal insulation and structural damage – all using a non-contact method! The testo ScaleAssist function, which automatically ensures optimum setting of the thermal image scale, means you get objectively comparable thermal images of buildings. This makes correct assessment of structural defects and thermal bridges easier than ever before. Checking the air tightness of windows and doors is one of the typical applications of the thermal imager.
Easy checking of heating and installation systems
Testo thermal imagers are easy and intuitive to operate, so they are ideal for quickly and reliably checking heating, ventilation and air conditioning systems. Just a quick look with the thermal imager is enough to discover irregularities in temperature distribution. Thus, thermography can be used to easily locate clogged radiators and leaks. Typical applications for the thermal imager:
- Checking radiators for silting
- Locating leaks
- Measuring the flow and return temperature
- Pinpointing the course of heating loops in an underfloor heating system
On the trail of a ruptured pipe
If a pipe rupture is suspected, the only solution left is often to break open entire wall or flooring areas. The thermal imager enables you to minimize damage and reduce costs, because you locate precise leaks in underfloor heating and other inaccessible pipelines. This avoids opening up walls and floors unnecessarily and considerably reduces the repair costs.
