Key Features

  • Widest temperature ranges for most flexible process adaptation
  • Highest accuracy and repeatability in its class
  • Fully digital core for sub-ranging and adopted analog output
  • Response time of 120 μs for very fast and highly dynamic processes
  • High-end optics with manual focus capability
  • 4 digit LED display
  • Robust, stainless steel sensor for harsh environments (IP65/NEMA4)


The pyrometer IGA 6 Advanced is a digital, compact, and fast infrared measuring instrument for non-contact temperature measurement on metals, ceramics, or graphite.

For a precise alignment of the pyrometer to the measuring object, the instrument is optionally equipped with a laser targeting light or a view finder.

The pyrometer can be connected to a PC through an RS485 to USB connection, enabling you to make parameter adjustments using the InfraWin software. The software can be used for temperature indication, data logging, and further analyzing of complete temperature processes.

  • Induction processes (e.g. Hardening, Welding, Brazing, Soldering etc.)
  • Heating and cooling processes
  • Melting 
  • Casting
  • Annealing
  • Rolling
  • Forging
  • Sintering
