Helium low temperature thermometer

WebThe Provisional Low Temperature Scale ( PLTS-2000 ), adopted by CIPM in 2000, covers the temperature range from 0.9 mK to 1 K. Since ITS-90 and PLTS-2000 differ in their overlapping range (from 0.65 to 2 K), a new 3He vapor pressure scale ( PTB-2006) was adopted. This scale passes into the ITS-90 above 2 K, and into the PLTS-2000 below 1 K. WebFor measurement of still lower temperatures—4.2 K to 0.9 K—the zero point pressure of 10 cm to 0.2 cm of mercury is employed and the mercury manometer is replaced by the …
