The Impac® IN 6/78 pyrometer is designed specifically for non-contact temperature measurements on thin glass surfaces in ranges between 150 and 1100°C. The special 7.8 μm wavelength makes it possible to accurately and reliably measure glass sheets below 1 mm thickness (ultra-thin glass).

The version IN 6/78-L is equipped with optics with a better field of view for the measurement of small objects. The high-speed version IN 6/78-H has a shorter exposure time of only 30 ms and is suited for fast-measuring tasks.


  • Achieve high accuracy with the fully digital core sensor design
  • Easily integrate with a small, stainless steel housing
  • Connect to a PC via RS485 to USB connection for further analysis
  • Use in ambient temperature up to 70°C without cooling


  • Anti-reflective lens created with semiconductor material to reduce environmental sensitivity
  • Multiple onboard digital and analog interfaces for direct and fast PLC communication
  • Adjustable emissivity (10 to 125%) and transmittance (10 to 100%) in steps of 0.1%
  • Adjustable subrange

After the initial warm-up, enhanced optics and electronics virtually eliminate zero drift  and feature precision-beam collimation. A comprehensive operating system allows you to tailor the device to multiple operations. And calculations are performed in realtime for transmission to your host system.
