Klasmeier calibration service

In our DAkkS laboratory, we calibrate temperature standards with excellent small measurement uncertainties. With our specialization in the temperature parameter, we can guarantee highly precise calibrations with short turnaround times of 5 – 7 working days.



  • Temperature fixed points from -189 °C to 961 °C
  • comparison calibration at -196 °C and from -80 °C to 1200 °C
  • triple set of temperature fixed points
  • Excellent measurement uncertainty
