The testo 872s thermal imager is ideally suited for professional industrial and building thermography - at the same time it ensures your work is both quick and easy. It is versatile to use, for example in industrial and mechanical maintenance or for detecting structural defects. You can generate error-free and objectively comparable infrared images using its handy functions. The IFOV warner, testo ɛ-Assist and testo ScaleAssist mean you can avoid measurement errors and not only effortlessly achieve optimum setting of emissivity (ɛ) and reflected temperature (RTC) for building thermography, but also of thermal image scale.

Features:

  • Highest image quality thanks to high resolution: 76,800 temperature measuring points for precise thermography. Infrared resolution of 320 x 240 pixels – extendible to 640 x 480 pixels via integrated SuperResolution Technology
  • Detecting temperature differences from as little as 0.09°F (0.05°C)
  • testo Thermography App to use mobile terminal devices as a second display and for remote control or to write and send reports, along with saving them online
  • Wireless communication thanks to Bluetooth – this means you can also wirelessly integrate the readings of the testo 605i thermohygrometer
  • Built-in digital camera generates a real image in parallel to the thermal image
  • Integrated laser marker – can also be precisely visualized as a measuring point in 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 of the thermal insulation behaviour of buildings
  • 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.
  • Image quality with IR resolution of 320 x 240 pixels (640 × 480 pixels with testo SuperResolution technology)
  • Thermal sensitivity of 0.09 °F (0.05 °C)
  • Recording and documentation of ambient conditions with the testo 605i Smart Probe ThermohygrometerIntegrated laser marker – can also be precisely visualized as a measuring point in the thermal imageAutomatic detection of hot and cold spotsFree analytical software for creating professional reports
