✦ Synopsis

A simple system for measuring electrical resistance R versus temperature T in the range 1-20 K is described.

It is based on the use of a lock-in amplifier SR 510 (Stanford Research) interfaced with a personal computer IBM AT. Measurements in the range 10 M9~-1 k~ dissipating 1 nW-0.1 pW with an accuracy better than 1% can be carried out on eight samples at the same time.
