The digital Impac® IPE 140 pyrometers are highly accurate. They offer different focusable optics with extremely small spot sizes. Parameters can be selected via an integrated keypad and settings are indicated on a built-in LC-display. In measuring mode, the actual temperature is indicated.


  • Easily select parameters via keypad
  • Reduce emissivity errors
  • Safely mount and accurately align
  • Detect small objects


  • Test current output
  • Housing with precision mounting rail for safe mounting and accurate alignment
  • Interface RS232 / RS485 switchable
  • Focusable optics
