Testo 868 thermal imaging camera
+ Freight and GST
The testo 868 thermal imager is characterized by its professional measuring performance and its easy handling. It has the best thermal image quality in its class, an integrated digital camera and impressive smart functions. The case supplied with the thermal imager means it can be conveniently transported, so it is always there for you when needed.
• Very good image quality: IR resolution of 160 x 120 pixels, via integrated testo SuperResolution Technology 320 x 240 pixels
• Smart and networked: the free testo Thermography App enables you to write and send reports on site, as well as saving them online, and lots more.
• Integrated digital camera
• Innovative functions, such as testo ScaleAssist, for comparable thermal images in building thermography
With the testo 868 thermal imager, we have developed a thermal imager which makes work quicker and easier – without foregoing professional thermal imaging technology. You can generate error-free and objectively comparable infrared images using its handy functions. The IFOV warner, testo ?-Assist and testo ScaleAssist mean you can avoid measurement errors and not only effortlessly achieve optimum setting of emissivity (?) and reflected temperature (RTC) for building thermography, but also of colour scale.

Detecting structural defects and ensuring building quality (also for images of the building shell)
Analysis with the Testo thermal imager is a fast and efficient method of detecting possible structural defects. Furthermore, the thermal imager is also ideally suited for providing proof of the quality and correct implementation of construction measures. Any heat losses, humidity and lack of air tightness arising in a building are visible in the thermal image. The Testo thermal imager offers the possibility of detecting structural damage and implementation defects in the thermal insulation – 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. Detecting insulation defects and thermal bridges in the building shell is one of the typical applications.
Carrying out detailed energy consultancy
In building thermography, infrared technology is ideally suited for the fast and effective analysis of energy losses in the heating or air conditioning of buildings. Thanks to its high temperature resolution, the thermal imager provides detailed images of inadequate insulation and thermal bridges. It is impressive in terms of recording and documenting energy losses on outer windows and doors, roller blind casings, radiator niches, roof constructions or the entire building shell. The thermal imager is the best measuring instrument for comprehensive diagnostic and maintenance uses and always a good choice when it comes to energy consultancy.
Easy checking of heating systems and installations
Heating, ventilation and air conditioning systems can be quickly and reliably checked thanks to the easy and intuitive operation of the Testo thermal imager. Just a quick look with the thermal imager is enough to discover irregularities in temperature distribution. Thermography can therefore be used to easily locate clogged radiators and leaks.Typical applications for the thermal imager:
- Pinpointing the course of heating loops in an underfloor heating system
- Checking radiators for silting
- Measuring the flow and return temperature
Investigating moisture damage
Not every damp wall is caused by a faulty water pipe. Water can rise or penetrate due to faulty installation of rain and water run-off systems, causing wet walls. Moisture damage can also occur due to blocked drains or insufficient seepage. The thermal imager finds the cause of rising damp or penetrating rainwater straight away, thus preventing greater damage.
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.
