详情

The pyrometer IGAR 320 measures in the 2-color method (ratio method) in which two adjacent wavelengths are used for the temperature determination.

This technique offers the following advantages compared to standard 1-color pyrometers:

  • The temperature measurement is largely independent of the object’s emissivity and in wide ranges unaffected by dust and other contaminants in the field of view.
  • The measuring object can be smaller than the spot size and measurements through dirty viewing windows are possible up to a certain contamination.

The pyrometer can also be switched to 1-color mode and used like a conventional pyrometer.

The included InfraWin software enables graphical display and storage of measurement values, as well as easy set-up of all instrument parameters.

Typical Applications

  • Metal Processing - Induction Processes: Hardening, Welding, Forging, Brazing, Soldering, etc.
  • Metal Processing - Noble Metals Melting and Purifying
  • Metal Processing - Wire/Rod Mill Water Box Measurement, Laying Head & Air Cooling Conv
  • Vacuum Processes - e.g. Coating, Brazing, etc.
  • Sintering
  • Laser Applications
