HSL now supplies the RO-600 Ruthenium Oxide Thermometer down to 20mK. Moreover, grouped / interchangeable is available and have a nominal resistance of 1kΩ at ambient temperature.
Ruthenium oxide temperature sensors also offer excellent performance characteristics in magnetic field environments. These sensors exhibit an initial small negative magnetoresistance at temperatures below 250 mK at low fields (less than ~1.5 Tesla).

Furthermore, the magnetoresistance becomes positive at larger fields and increases at lower temperatures. This magneto-resistance is repeatable. If an 8 Tesla field induces a resistance change of 8% at 80 mK, this reflects a 7mK error.
We have observed the orientation dependence of the sensor mounting versus field direction. Ruthenium Oxide sensors are also available in the uncalibrated, grouping, or calibrated units. They feature excellent reproducibility, fast thermal response time, and miniature size at a reasonable cost.
