The Impac® IN 510 and IN 520 digital pyrometers each have a separate, stainless steel miniature sensor head. The sensor head/cable of the 510 models are usable in ambient temperatures without cooling up to 85°C. The sensor head/cable of the 520 models are usable in ambient temperatures without cooling up to 180°C. The 520 models can also be used as a temperature switch.

The IN 510-N, IN 510, IN 520-N, and IN 520 are digital pyrometers for non-contact temperature measurement of non-metallic or coated metallic objects.

The versions IN 510 and IN 520 are equipped with an illuminated LC display that shows the actual temperature reading. The types IN 510-N and IN 520 do not have a display and keyboard and are parametrized via interface.


  • Install in small, harsh industrial environments
