Product overview

Thermal imagers made in Germany

All Testo thermal imagers are developed and produced in Germany. The ultra-modern site Titisee includes laboratories for researching basic technologies as well as the measuring technology and design development departments. The result: innovative features and outstanding 'made in Germany' quality.

Building thermography

For some years thermography has been an indispensable diagnostic instrument in energy consultation, in tracking down structural defects or checking heating equipment and installations. Thanks to their outstanding thermal sensitivity, Testo thermal imagers are able to detect even the most minor defects or damage.


With thermal imagers from Testo, you can detect thermal anomalies in maintenance easily, efficiently and safely. As well as preventive mechanical and electrical maintenance, you can also check the fill level of sealed fluid tanks, for example.

Production quality

Thermographic measurements play a valuable role in production, both in quality control and in quality assurance. Thanks to the non-contact infrared technology of the thermal imager, measurements can even be carried out without interrupting production.

Research and development

In research & development, thermal imagers can be used to measure heat development over specific time periods – in microelectronics for example – as well as for the non-contact measurement of surface temperatures.
