Pt100 Type N Medium Temperature Precision Thermometers
The eXacal precision thermometers are used for precise temperature measurements or as calibration standards.
- Temperature range: -100 °C to 420 °C
- small measurement uncertainties: 6 mK to 21 mK
- robust alternative to ITS-90 standard thermometers
- high stability and good calibration capability
- Small measurement uncertainties with DAkkS calibration certificate
The thermometer can be calibrated at fixed temperature points with smaller measurement uncertainties.
Calibration
eXacal thermometers are calibrated in our own DAkkS calibration laboratory. The DAkkS accreditation ensures that all calibrations are traceable to national and international standards.
The calibration of eXacal resistance thermometers is carried out at ITS-90 fixed points. It is also possible to carry out calibrations according to the comparison method in liquid baths and calibration furnaces. The measurement uncertainty is calculated from many components. The largest contributions are reproducibility, ITS-90 function, self-heating and hysteresis.
Measurement Uncertainties
- Small measurement uncertainties with DAkkS calibration certificate
