The Impac® series 8 pro pyrometers are high-quality, battery-driven portables for non-contact temperature measurement. Thanks to full digital processing, they offer wide temperature ranges and high accuracy and measuring results can be shown and analyzed directly on site.

For high temperatures, the Impac IS 8 pro is available in two temperature ranges between 600 and 2500°C. For medium temperatures, the Impac IGA 8 pro offers a range from 250 to 1600°C. The Impac IS 8-GS pro is a special version for use in foundries.


  • Use daily in rough industrial conditions
  • Easily adjust to small spot sizes
  • Enable short response times (1 ms) for exact measurement of fast-moving objects
  • Store large amounts of measuring data for subsequent analysis


  • Very robust aluminum die-cast housing for use in harsh environments
  • Focusable precision optics for adjusting to the smallest spot sizes
  • Temperature display on the housing, in the viewfinder and on the multifunctional display
  • Integrated maximum value storage to determine the peak value achieved during a measuring series
  • USB interface for using the optional analyzing software PortaWin

Select specifications are shown below. Please see product data sheet for additional specifications.
