The mobile CellaCast PT 180 was specially developed for measuring the temperature of liquid metals. It is used to continuously monitor the temperature of the melt in the channel of a blast furnace, cupola furnace or automatic casting machine. This is made more difficult by the fact that, due to the plant, measurement is often only possible from a great distance. The special feature of the CellaCast PT 180 is the high-resolution optics and thus a small measuring field. This allows reliable measurement even from a distance of 30 m.
