  • Infrared resolution 240 x 180 pixels
    with testo SuperResolution technology 480 × 360 pixels
  • Thermal sensitivity (NETD) of < 0.08 °C (80 mK)
  • With testo Thermography App for on-site analysis and report generation
  • Integration of further measurement parameters via Bluetooth
  • Automatic detection of hot and cold spots
  • testo ScaleAssist for comparable images in building thermography
  • Integrated 5 MP digital camera
  • IFOV warner for displaying the measurement spot size

Testo 871 – Smart thermography for professional demands.

The testo 871 thermal imager offers a high-quality 240 x 180 pixel detector, connectivity via the testo Thermography App and numerous innovative functions. It fits comfortably in the hand and convinces with intuitive operation in a modern tile look.

For even more meaningful thermal images, the thermal imager also wirelessly integrates the measurement
values of the clamp probe testo 770-3 as well as the thermohygrometer testo 605i (both available as an option).

Features Testo 871

  • Very good image quality due to high resolution: 43,200 temperature measuring points for precise thermography. Infrared resolution of 240 x 180 pixels – extendible to 480 x 360 pixels via integrated SuperResolution Technology
  • Detecting temperature differences from 0.09°C
  • The testo Thermography App enables you to write reports on site, save them online and send them by e-mail, as well as allowing you to use mobile terminal devices as a second display or for remote control
  • Wireless communication thanks to Bluetooth – this means you can also wirelessly integrate the readings of the compatible testo 770-3 clamp meter and testo 605i thermohygrometer
  • Built-in digital camera generates a real image in parallel to the thermal image
  • Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
  • The testo ScaleAssist automatically ensures optimum setting of the thermal image scale, which means you generate objectively comparable and error-free thermal images, for example the thermal insulation behavior of buildings
  • The testo ɛ-Assist ensures the correct measurement result by automatically determining and setting the emissivity and reflected temperature
  • The IFOV warner means the distance from the measurement object/measurement spot size is determined and the measurement spot is shown on the thermal image – you, therefore, avoid measurement errors because the camera shows you exactly what you can measure
  • Pro software for image evaluation on the PC
  • You can choose to save thermal images as JPEGs
