- Model IS 8-GS Pro - Portable Digital Pyrometers for Non-Contact Temperature Measurement



Portable digital pyrometers for non-contact temperature measurement in foundries between 1000 and 2000 °C. The pro series is a revision of the 15 years proven plus series. The instruments feature fully digital signal processing, resulting in wider temperature ranges as well as higher accuracy. With the additional integrated graphic display the measuring results can be shown and analyzed directly on site.

  • Very robust aluminum die-cast housing for use in rough environments
  • Focusable precision optics for adjusting smallest spot sizes
  • Temperature display on the housing, in the view finder and on the multi-functional display sideways
  • Large data storage for subsequent analysis of measuring data
  • Integrated maximum value storage to determine the peak value achieved during a measuring series
  • Extremely short response time for measurements on fast-moving objects
  • USB interface for using the optional analyzing software PortaWin
  • The series 8 pyrometers are high-quality, battery driven portables for non-contact temperature measurement.

The aluminium die-cast housing is specially designed for the daily use under rough industrial conditions. The easy focusable precision optics provides small spot sizes for measuring distances between 500 mm and ∞. The bright, optimized view finder with exact spot indication and built-in temperature display facilitates the accurate aiming on the object. Moreover, the large measurement data storage offers the best possibility for subsequent interpretation of the measured values.

The extremely short response time of 1 ms allows exact measurements of fast moving objects and a very quickly detection of temperature differences. The maximum temperature can be stored in the built-in peak picker (maximum value storage).

For high temperatures the IS 8 pro is available in two temperature ranges between 600 and 2500 °C, for the medium temperatures the IGA 8 pro with a range from 250 to 1600 °C. The IS 8-GS pro is a special version for use in foundries.

The instruments are mainly used in foundries.
