As a specialist for costumized system solutions we realize complex projects including project planning, software, installation, startup and maintance.

Product range DIAS Infrared

Our offer - a huge product range for non-contact temperature measurement

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

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

Non-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.Please read this article for more information.
