2.476,00 3.710,00 

Manufacturer: Klasmeier / eXacal
Model: Pt100HS


Precision resistance thermometer model eXacal Pt100HS. With protective sheath of gas-tight ceramic and hand-made 100 Ohm ceramic temperature detector.

  • Temperature range: 0 °C to 850 °C
  • stable high temperature thermometer with good calibration capability
  • Protective sheath from gas tight ceramics
  • small measurement uncertainties with DAkkS calibration certificate
    The thermometer can bei calibrated at temperature fixed points with small measurement uncertainties. 


eXacal thermometers can be calibrated in our own DAkkS calibration laboratory. The DAkkS accreditation ensures that all calibrations are traceable to national and international standards.

The calibration of the eXacal resistance thermometers is done by at ITS-90 fixed points. It is also possible to make calibrations according to the comparison method in calibration baths and calibration furnaces. The measurement uncertainty is calculated from many components. The largest contributions are reproducibility, ITS-90 characteristic, self-heating and hysteresis.

  • small measurement uncertainties with DAkkS calibration certificate
  • temperature fixed points up to Aluminium-Meltingpoint 660,323 °C
  • ITS-90 standard thermometer at comparison calibration
