The Impac® IN 300 stationary pyrometer is designed for non-contact temperature measurement of non-metallic surfaces or painted, coated, or anodized metals between -20 and 600°C.

The small housing dimensions allow for easy integration of the pyrometer into compact production machines and the two-wire technique simplifies electrical connection.


  • Install in small, harsh industrial environments
  • Use in ambient temperature up to 70°C without cooling
  • Adjust emissivity between 40 to 100%
  • Benefit from two-wire technique


  • Easy electrical and mechanical installation
  • Very small housing dimensions
  • Stainless steel housing
  • Small spot sizes (distance ratio 15:1)
  • Suitable for the food industry
