Details

The IGA 320/23 is a short wavelength infrared measuring instrument with internal digital signal processing. It is used for measurements of metallic surfaces, graphite and ceramics, etc.

The very small housing dimensions enable the integration of the pyrometer into compact production machines and the solid and robust design guarantees reliability even in rough industrial environments.

The instruments are equipped with a choice of optics for small spot sizes. Using an additional close-up lens these spot sizes can be reduced even more, with a measuring distance 50 or 120 mm.

The LED targeting light enables precise alignment on the measurement object. It is automatically active and can be used during measurement.

Additional to the analog output the pyrometer is equipped with a digital RS485 interface. This enables secure data transmission to a PC or an PLC, over long distances. The provided InfraWin software enables the graphical display and storage of measurement values; plus the setting of all instrument parameters.
