You get the complete solution line-up of non-contact temperature measurement technology from one source. DIAS develops and manufactures its products in Germany. DIAS offer you an individual and professional consulting service around your measurement task. As a specialist for costumized system solutions DIAS realize complex projects including project planning, software, installation, startup and maintance.

A huge product range for non-contact temperature measurement:

  • Infrared camera series PYROVIEW for measuring temperature distributions
  • Infrared line camera series PYROLINE for recording of temperature profiles
  • Pyrometer series PYROSPOT for spot temperature measurement

In addition, DIAS offer a variety of accessories, special products from simple temperature switch to complex system solutions, for example, for early fire detectionsoftwarecalibration sources and services.

DIAS also develop and manufacture special infrared sensors and arrays, not only for non-contact temperature measurement, but also for gas analysis and spectroscopy.


Infrared image of a motor - process controlNon-contact temperature measurement – your benefit

  • Non-destructive measurement
  • Continuous real-time observation of your process
  • Measurement at parts that are difficult to access
  • Temperature measurement over small and large distances
  • Measurement of fastchanging temperatures
  • Measurement of extreme high temperatures (up to 3000 °C)
  • Temperature measurement on aggressive materials as well as in electro magnetic fields


Which spectral ranges does suit to which application?

Principle: Measure at wavelengths as short as possible to minimize temperature measurement errors resulting from emissivity inaccuracies.
