DAkkS calibration of temperature fixed points
Temperature fixed points are calibrated by comparison with reference temperature fixed points using highly stable standard resistance thermometers (SPRT). The temperature fixed point calibration is provided with a DAkkS calibration certificate as standard.
- All types of ITS-90 temperature fixed points (slim and primary temperature fixed points, ISO towers).
- Water triple point cells of any design
- Heat-pipe set-up
- Highly stable SPRT’s and MicroK Gold as measurement technology
