Metis “Self Contained” Pyrometer Series

Two-Color Pyrometer Metis MQ11 and MQ22

Two-Color- or Ratio- Pyrometers are typical names for pyrometers which measure temperatures from the ratio of radiation signals of two adjacent wavelengths as opposed to measuring the absolute intensity like single wavelength units do. The advantages for customers are the following:

  • Gray bodies, i.e., targets with the same emissivity on both wavelengths, can be measured without emissivity setting.
  • There is automatic compensation for dust, smoke or a dirty viewing window between pyrometer and target.
  • Temperature errors are minimized if the target is too small or moving and the field of measurement can’t be completely covered.

Metis Two-Color Pyrometers have universal applications, which means that they can also be used as two-color pyrometers as well as single wavelength pyrometers. In single wavelength mode, customers have the choice of deriving the analog output signal from shorter or longer wavelengths, or both. Using digital communication these temperature measurement results can be recorded and compared, to determine quickly whether the target is a „gray body“ radiator or not.
