The testo 875-1 infrared camera’s technical features

The testo 875-1 thermal camera is the entry-level model in the testo 875 series. It is impressive not just thanks to its intuitive operation, but also to these technical features:
  • Resolution and image quality: Detector size 160 × 120 pixels = 19 200 temperature measuring points. SuperResolution Technology enables you to take image quality right up to the next level of 320 × 240 pixels in next to no time. Four times as many readings and a geometric resolution that has been improved by a factor of 1.6 mean you get even more detail and even greater reliability with measurements
  • Thermal sensitivity < 80 mK: Thanks to a temperature resolution of < 80 mK, even small temperature differences can be seen
  • High-quality 32° × 23° lens: The lens with its manual focusing enables a wide field of view and an ideal overview of the temperature distribution, along with precise focusing on the object being measured
  • Automatic hot/cold spot detection: Critical temperature conditions are directly displayed
  • Solar mode: The solar radiation value can be input into the thermal imager and stored with each thermal image
  • Pro software for image evaluation on the PC included. You can also choose to save the thermal images as JPEGs. Find out more about the pro software
  • Measuring range: -20 to +280 °C
