Infrared thermography applications

Testo Infrared Cameras are a valuable and versatile tool suitable for many applications. The visualisation of temperatures using thermography can be used in the following fields:

  • In building thermography a Testo thermal camera helps you to detect thermal bridges and structural defects.
  • In heating engineering you can use thermography to check underfloor heating is working properly or for the non-destructive detection of leaks.
  • In maintenance a thermal camera enables you to see wear before systems fail.
