The thermal imager – your new favourite tool

The measuring instrument for every application: there are hardly any measuring instruments that are as versatile as a thermal imager. Because the areas where the visualization of temperatures using thermography makes your work easier include the following:

  • 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.

NEW: Thermal imager testo 883

See for yourself.

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

  • Resolution: at least 160 x 120 pixels
  • Thermal sensitivity < 120 mK (visualizes temperature differences as from 0.12°C)
  • Software for analysis and professional reports
  • Easy and intuitive operation

testo 883 thermal imaging camera + SiteRecognition

The testo 883 thermal imager features an impressive infrared resolution of 320 x 240 pixels – which can even be expanded to 640 x 480 pixels with the built-in testo SuperResolution technology.

In addition, you always have full control over the thermal image thanks to the manual focus.

The testo SiteRecognition technology guarantees fully automatic site recognition, as well as storage and management of the thermal images. This rules out any mix-ups, prevents errors during evaluation and saves time by eliminating the need for manual image assignment.

Smart temperature measurement

Smart Probes are compact professional measuring instruments operated by smartphone. They are available for the most important measurement parameters and will make your day-to-day work somewhat more pleasant.

Measuring temperatures on surfaces

As the name makes clear, a surface temperature meter is used to measure the temperature on the surface of a measurement object. This category also includes infrared thermometers. Just like an infrared thermal imager, they measure an object's thermal radiation. Temperature measuring strips on the other hand are used for fast measurement of the surface temperature in a really wide variety of applications.

Recording temperatures

Temperature data loggers are used not only for measuring temperatures (and other measurement parameters), but also for monitoring and recording them over defined time periods.
