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

Would you like to buy a thermal imager?
What to keep in mind:

Thermal imager comparison
  • 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

Infrared thermography applications

FOV calculator

The FOV calculator shows you quickly and easily how small the measurement object can be, in order to be recognized (IFOV geo) and reliably measured (IFOV meas) at the selected distance.

Functions for the Testo thermal imagers

Buying a thermal imager is a sensible investment. Especially if you choose a Testo thermal imager. Because our instruments have the best price-performance ratio of their class. That’s why they are the best way you can use infrared thermography for your purposes – thanks to these features:

testo IRSoft

testo 872 thermal imager – A thermographic camera for all tasks

Thermal imager testo 872

Building thermography

With the testo 872, there are no longer any thermal bridges, missing insulation or leaks in underfloor heating that remain undetected. Simply switch on, get going and know more.

Photovoltaic thermography

One look with the testo 872 and you can see whether your system is running efficiently or which faulty modules need to be replaced. That means your investment pays for itself faster and your photovoltaic system produces electricity efficiently.

Smart thermography with the highest image quality – this is what the testo 872 model stands for:

  •  Infrared resolution 320 x 240 pixels (with testo SuperResolution technology 640 x 480 pixels)
  • Integrated digital camera and laser marker
  •  Wireless measurement data transfer from the testo 770-3 clamp meter and testo 605i humidity measuring instrument
  • With testo Thermography App

Instead of thermal imaging cameras: more measuring instruments from Testo

More measuring instruments for temperature measurement from Testo

Depending on the application, you will still need more measuring instruments for efficient temperature measurement in addition to a thermal camera. We have put together a small selection of our bestsellers for you here.

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.

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.

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.
