Key Features

  • Sensor head and cable usable in ambient temperature up to 85 or 180 °C without cooling
  • Sensor head exchangeable without recalibration
  • Close focus lens for small objects
  • Switchable digital interface RS232 / RS485
  • Isolated relays contact
  • Selectable analog output
  • Setting of parameters via keyboard or interface


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

The versions IN 510 are equipped with an illuminated LC display which shows the actual temperature reading. All available parameters can be set via the integrated keyboard. The types IN 510-N do not have display and keyboard, they will be parametrized via interface.

All pyrometers are equipped with a stainless steel miniature sensor head, the field of view is 10:1 or 2:1, they can be used in ambient temperatures up to 85 °C or 180 °C without cooling dependent on the type.
