Pt100 Model HS High-Temperature Precision Thermometers
Precision resistance thermometer model eXacal Pt100HS. With protective sheath of gas-tight ceramic and handmade 100 Ohm ceramic detector.
- Temperature range: 0 °C to 850 °C
- stable high temperature thermometer with good calibration capability
- Protective sheath made of gastight ceramic
- 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
