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 (SPRT). As standard, temperature fixed point calibration is 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)
Triple point of water cells of any design
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 working days or by arrangement.
