Impac IN 6/78 Pyrometers


Accurate, rugged and reliable pyrometer for non-contact temperature measurements on thin and thinnest glass sheets. Temperature ranges between 150 and 1100 °C.


Specifically engineered for non-contact temperature measurements on thin glass surfaces, the Impac® IN 6/78 pyrometer operates efficiently in ranges between 150 and 1100 °C. Its unique 7.8 μm wavelength enables precise and dependable measurements of ultra-thin glass sheets under 1 mm in thickness. The IN 6/78-L variation offers enhanced field-of-view optics ideal for small object measurement, while the high-speed IN 6/78-H model, with a rapid exposure time of just 30 ms, is perfectly tailored for quick-measuring tasks.


  • Anti-reflective lens created with semiconductor material to reduce environmental sensitivity
