Thermal camera

Make temperature differences visible

Thermal camera

Every body above absolute zero radiates heat, which can be visualized using a thermal camera. The thermal camera makes this feat possible, as it displays different temperature ranges in different colors. Building thermography relies on the use of this technology and uses the thermal camera for building diagnostics and to make thermal bridges in the building visible, for example.

In heating construction, thermography can be used to check the function of underfloor heating systems or to detect leaks in a non-destructive manner. In maintenance, wear and tear can be seen before systems fail. Without a modern thermal camera, time-saving and effective troubleshooting is hardly possible today.

Thermography offers the following advantages:

  • Representation of temperature distributions or differences in an image

  • Clarification of areas of increased temperature in systems


  • non-contact measurement by infrared camera

  • Detection of different objects in dark surroundings

Thermography: an important test in homes and industry

Temperatures can be measured with a normal thermometer. However, this is only possible at one point at a time. When monitoring a large area, constant point measurements would require a disproportionate amount of effort and would therefore be very expensive. The thermal camera, on the other hand, displays temperatures directly in an image, as it records the distribution of the temperature on the surface. This means that certain areas or several objects stand out separately because they differ from comparative temperatures.

The thermal camera uses infrared radiation to display temperature differences.

Thermal cameras: Important points when selecting

Testo offers various models of thermal cameras so that the right model can be found for every area of application. Whether for daily use on the construction site or for highly professional applications in industry, the thermal camera is supplied in the desired configuration. When choosing, it is important that you pay attention to the following things:

  • Resolution must be at least 160 x 120 pixels

  • Simple/intuitive operation

  • Versatile PC software for analysis and documentation

Measuring the temperature with cameras?

The thermal camera measures temperatures and records them, making differences clear and thus facilitating the evaluation of building inspections, for example. The camera from Testo has various features and, thanks to SuperResolution, can display significantly better and clearer images.

Other features include:

IRSoft: Analysis of data from thermography

SiteRecognition: It combines measurement recognition and image management for recurring measurements of similar measurement objects and manages the images of a measurement location in a database

Panorama image assistant: Display large objects on one image

testo SuperResolution

testo SuperResolution: Recognize more details

This will improve your thermal images by a class in no time at all.

Particularly practical for preventive maintenance.

Buy a thermal imaging camera: Tools from Testo

Testo not only offers the right thermal camera for your application, but also an entire process analysis package. This allows you to track, save and evaluate the development of the measured temperatures. Testo Scale Assist on the testo 865 and 872 prevents misinterpretations, as it automatically scales comparable thermal images. With the help of Testo E-Assist on the models mentioned, the emissivity and the reflected temperature are set automatically. All in all, every thermal camera from Testo offers all the necessary features to work in the selected area or to use the thermal imager sensibly and profitably. Various models are available for different applications, which are suitable for beginners and all-rounders as well as models that meet the highest requirements as professional devices.
