The Impac® IGA 15 plus pyrometer is equipped with a laser targeting light. It features maximum value storage, minimum value storage, average and difference function, and an acoustic alarm. High quality optics enable you to measure small objects starting at 4 mm. You also can combine with the closeup lens to measure from 1.25 mm. With the short exposure time of only 20 ms, fast moving objects can be easily and accurately measured.


  • Enable high accuracy at an affordable price
  • Measure fast-moving objects
  • Easily measure small objects with high quality optics
  • Store data
  • Switch between Celsius and Fahrenheit temperature scales


  • Fast temperature detection, only 20 ms
  • Small object measurement from 1.25 mm
  • Integrated additional functions
  • USB interface
  • Analyzing software PortaWin (optional)
