2 Introduction
2.1 Appropriate use
The IS 8 pro and IGA 8 pro pyrometers are high-quality, battery powered portables for non-
contact temperature measurement between 250 and 2500 °C, dependent on the type. The
instruments have full digital signal processing, which results in long measurement ranges as well
as very high accuracy. The instruments are mainly used in the steel, glass, forging industries as
well as in foundries. 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 is available in two
temperature ranges between 250 and 2000 °C.
The IS 8-GS pro is modified for the use in foundries. It is specially designed for non-contact
temperature measurement of molten metals in the range of 1000 to 2000 °C. In casting
processes, the correct measurement can only be obtained on the pouring stream to avoid the
influence of slag. The specially selected wavelength in the near infrared facilitates this accurate
temperature measurement as molten metals have their maximum emissivity in this spectral
range. Additionally, the influence of changing emissivity is reduced in this range and the
interference of the measurement by atmospherical absorption is avoided. A longer response
time of 0.5 s prevents the possible influence of hot sparks.
