Technical highlights of the testo 865 thermal imager

The testo 865 thermal imager stands out thanks to its easy operation and has the following impressive technical features:
 
  • Very good image quality due to high resolution: 19,200 temperature measuring points ensure precise thermography. Infrared resolution of 160 x 120 pixels – via integrated SuperResolution Technology 320 x 240 pixels
  • Visualize temperature differences from 0.12°C
  • Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
  • 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
