A superconductive reference device (SRD1000), providing 10 reference points in the temperature range 10 mK–1 K with dedicated measurement electronics, has been developed and tested to provide direct traceability to the new provisional low temperature scale (PLTS-2000). We report on the repeatability of the transition temperatures of samples of IrxRh100−x alloys (with transition temperatures between 20 and 100 mK) and some single crystals (Cd, Zn, AuIn2,AuAl2 and W).
