he 5686 complies completely with ITS-90 and has the following resistance ratios:
 
W(302.9146 K) ≥ 1.11807
and
W(234.3156 K) ≤ 0.844235
 
The 5686 covers temperatures from –260 °C to 232 °C, so it’s perfect for cryogenic applications. It is 5.8 mm in diameter and 56 mm long. Fixed-point calibrations are available for the model 5686 from –200 °C to 232 °C.
 
These SPRTs are small but meet customary SPRT performance for reproducibility, reliability, and stability. They solve many of the problems associated with taking precision measurements in situations unsuitable for traditional-length SPRTs.
