Key Applications

Thermal imaging can be used for a huge variety of tasks, across many different industries. From mechanical maintenance to checking freezer doors are correctly shut, the number of uses really is boundless. Here are just a few of the key applications thermal imaging is used for all over the world:


Detecting structural defects and ensuring construction quality

Analysis with a Testo thermal imager is a fast and efficient method of detecting possible structural defects. Furthermore, thermal cameras are ideal for providing proof of the quality and the correct implementation of construction measures. Any heat losses, humidity or areas of air permeability in a building will then be visible. The testo 869 makes it possible to detect faulty thermal insulation and structural damage – all using a non-contact method!

Typical applications:

  • Checking the air tightness of windows and doors
  • Finding insulation defects and thermal bridges in the building shell
  • Detecting and visualising areas that are prone to mould
  • Mapping underfloor heating systems



Thermal imaging is widely used to detect structural defects in buildings


Easy monitoring of heating and installation systems

Testo thermal imaging cameras are user friendly and easy to operate, so are ideal for quick checks of heating, ventilation and air conditioning systems. A quick glance is enough to discover irregularities in the temperature distribution. Thermography is the perfect solution for uncovering clogged radiators and leaks.

Typical applications:

  • Pinpointing the course of heating loops in an underfloor heating system
  • Checking radiators for the build-up of deposits
  • Measuring the supply and return temperature
  • Locating leaks


With a testo 869 you can visualise how well radiators are working


Checking as part of electrical maintenance

With electrical installations or cables in general, increased temperatures are always an indication of an overload, an imminent malfunction or an existing defect. Using thermal imaging you can evaluate the heat status of low, medium and high-voltage systems. Thermographic images lead to the early detection of defective components or connections, so the necessary preventive measures can be introduced in a targeted way. This therefore minimises dangerous fire risks and prevents costly production downtimes.

Typical applications:

  • Checking switch cabinets
  • Checking electrical connections
  • Monitoring and checking photovoltaic system
