  • Temperature measuring range +650...+1800 °C
  • Spectral range of 1,0 μm
  • Short response time of 1 ms
  • Smallest measuring spot: Ø 1,5 mm @ 110 mm

Fields of application

  • Temperature measurements requiring short measuring wavelengths
  • Precise and reliable measuring of metallic suraces in metal processing (e.g. welding, sintering) as well as metal oxides and ceramics


Due to their short measuring wavelength and the high temperature range of up to 2200°C the pyrometers of the DM401 series are ideally suited for high-temperature measurements of metals, metal oxides, and ceramics.
