Portable optical pyrometers

Portable optical pyrometers cover a wide range of possibilities. From measurements in applications for low temperature with our series of optical pyrometers T54 and T56 up to measurements of more than 3000 ºC for applications in steelworks or stained glass.

All series of portable pyrometers allow to connect to PC to download the recorded temperature measurements.

Series T54 and T56

Portable pyrometers type gun to measure temperatures easily and easily from -30 to 650 ° C for all types of surfaces.

The T54 portable pyrometers allow to adjust the emissivity depending on the characteristics of the material to be measured. In addition, the pyrometer T56 allows the connection of a K type thermocouple to adjust the emissivity automatically.

  • Our portable optical pyrometers are robust and easy to use
  • While pressing the button in a sweep can save the maximum, minimum or average temperature

Pyrometers with incorporated video

In some applications it is not possible to use lasers because the pointer can not be distinguished on materials with a very high luminosity as for example in metal castings. For this DIAS has developed portable pyrometers with embedded video
