The IS 8-GS plus manufactured by Impac is a special portable pyrometer for non-contact temperature measurement of molten metals in a temperature range of 100 to 2000°C. In casting processes the correct measurement can only be made on the pouring stream to avoid the influence of slag.
The specially selected wavelength in the near infrared range facilitates this accurate temperature measurement as molten metals have their maximum emissivity in this spectral range. Furthermore, the influence of changing emissivity is reduced in this range and the interference of the measurement by atmospheric absorption is avoided. A longer response time of 0,5 second prevents the possible influence of hot sparks.
Even for longer measuring distances the easily focusable precision optics achieves small spot sizes (for example, at a distance of 5 m the spot is only 16 mm) to allow larger safety distances between operator and pouring stream. The IS 8-GS plus is equipped with a switchable filter in the viewfinder to protect the eyes against the extremely bright radiation of the pouring stream.
Mecosa is the sole agent for Impac in South Africa.
