DAkkS Calibration of Temperature Fixed Points
Temperature fixed points are calibrated by comparison with reference temperature fixed points using highly stable Standard Platinum Resistance Thermometers (SPRTs). The temperature fixed point calibration is routinely provided with an accredited calibration certificate according to DIN EN ISO/IEC 17025 (DAkkS).
All types of ITS-90 temperature fixed points (slim and primary temperature fixed points, ISO towers)
Water triple point cells of all designs
Commissioning in heat pipes
Highly stable SPRTs and MicroK Gold as measurement technology
Measurement Uncertainties for an Accredited Calibration according to DIN EN ISO/IEC 17025 (DAkkS)
| Fixed Point | Temperature | Measurement Uncertainty |
| Mercury | -38.8344 °C | 2.5 mK |
| Water | 0.01 °C | 0.35 mK |
| Gallium | 29.7646 °C | 1.5 mK |
| Indium | 156.5985 °C | 4 mK |
| Tin | 231.928 °C | 5 mK |
| Zinc | 419.527 °C | 8.5 mK |
| Aluminum | 660.323 °C | 20 mK |
The minimum immersion depth of the thermometer is 190 mm (at -196 °C: 300 mm).
The maximum outer diameter is 8 mm.
The achievable measurement uncertainties depend on the test item.
Calibration duration approx. 5 business days or by arrangement.
Klasmeier Cloud Digital Archive:
Calibration documents quickly and easily accessible
The Klasmeier Cloud – the perfect storage system for all calibration documents. On all devices calibrated by Klasmeier, you will find a QR code that allows you to quickly and easily access our digital archive.
Particularly practical: In addition to all calibration documents, you will also find the contact details of the respective Klasmeier contact person there. This way, even in five or more years, you can find the information you need with a click if you have questions about your calibration product.
