Pirômetro IMPAC IGA 310 Front View

Key Features

  • Very small housing dimensions for easy installation, suited for use in confined spaces
  • 2-wire technique for current supply and temperature measurement at the same time
  • Internal digital signal processing for high accuracy
  • High quality optics for detection of small measuring objects
  • Built-in LED targeting light for easy alignment to the measuring object


The very small housing dimensions enable the integration of the pyrometer in compact production machines, the 2-wire technique ensures very easy electrical connection, and the solid and robust design of the instrument guarantees reliability, even in rough industrial environments.

The pyrometers are equipped with a connector for electrical installation, this offers the option to use connection cables up to 30 m.

For optimal match 3 different focusable optics with small spot sizes are available.
