Thermal Imagers

The measuring instrument for every application: there is hardly any device that is as versatile as a testo Thermal Imager.

Making temperatures visible with the help of thermography makes your work easier in these applications, among others:

  • In building thermography a Testo Thermal Imager helps you to detect thermal bridges and structural defects.

  • In heating construction, you can use testo Thermal Imagers to check the function of underfloor heating systems, or detect leaks non-destructively.

  • In maintenance a testo Thermal Imager enables you to see wear before systems fail.

Would you like to buy a thermal imager?
You should take the following into consideration:

  • Resolution: at least 160 x 120 pixels

  • Thermal sensitivity

  • Software for analysis and professional reports

  • Easy and intuitive operation
