The robust Impac® IS 310 and IGA 310 pyrometers feature streamlined dimensions to enable easy integration into compact production machines and they can be used in harsh environments.

The 310 series utilizes the two-wire technique and offers three focusable optics that showcase small spot sizes. To simplify electrical connectivity, the pyrometers are equipped with a connector that allows connection cables up to 30 m.


  • Enable high accuracy with internal digital signal processing
  • Detect small objects via high-quality optics
  • Use connection cables up to 30 m
  • Easily install
  • Operate in harsh environments


  • Small, robust stainless-steel housing for easy installation
  • Electrical connector
  • Two-wire technique for same-time current supply and temperature measurement
  • Internal digital signal processing for high accuracy
  • High-quality optics for measuring small objects
