From

0

Small, short wavelength digital infrared thermometer with fiber optics for non-contact temperature measurement between 85 and 1200 °C.

The IGA 320/23-LO is a short wavelength infrared measuring instrument with fiber optics and internal digital signal processing capabilities. This pyrometer is used for measurements of metallic surfaces, graphite and ceramics, etc.

For optimal match of the instrument to the application 2 different optics are available. The small dimensions of the optics allow easy integration into compact production machines.

The instrument is equipped with a fiber and an exchangeable optical head. The fiber and optical head are unaffected by electromagnetic interferences (e.g. induction) and can be used in high ambient temperatures up to 200 °C without additional
cooling.

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