OVERVIEW & SPECIFICATION

  • Very good image quality: Resolution 160 × 120 pixels / 320 × 240* pixels
  • Precise measurement: thermal sensitivity < 50 mK, high-quality 32° × 23° lens with manual focus, automatic hot/cold spot detection
  • Built-in digital camera creates a real image in parallel to the thermal image
  • Comprehensive accessories, including: robust case, pro software, SD card, carrying strap, mains unit and lots more

Ideally equipped for industrial and building thermography: The testo 875-1i thermal imager means even the smallest temperature differences can be seen with a thermal sensitivity of < 50 mK. You can create real images with the built-in digital camera and assign these to the thermal images.
