Laborat\u00f3rium elektrick\u00fdch transportn\u00fdch meran\u00ed je zameran\u00e9 na \u0161t\u00fadium elektrick\u00fdch transportn\u00fdch vlastnost\u00ed tuh\u00fdch l\u00e1tok v teplotnom intervale 1.8 \u0336 300 K. Merania elektrick\u00e9ho odporu je mo\u017en\u00e9 realizova\u0165 na materi\u00e1loch alebo \u0161trukt\u00farach v rozsahu odporov r\u00e1dovo od nano-ohmov a\u017e do giga-ohmov, pokr\u00fdvaj\u00fac tak rozsah viac ne\u017e 18 r\u00e1dov merania elektrick\u00e9ho odporu. To umo\u017e\u0148uje \u0161t\u00fadium \u0161irok\u00e9ho spektra materi\u00e1lov zah\u0155\u0148aj\u00fac supravodi\u010de, kovov\u00e9 syst\u00e9my, polovodi\u010de, ako aj mnoh\u00e9 syst\u00e9my v bl\u00edzkosti prechodu kov \u0336 izol\u00e1tor. Vzh\u013eadom na vysok\u00fa modularitu pr\u00edstrojov\u00e9ho vybavenia vyu\u017e\u00edvan\u00e9ho na merania elektrick\u00e9ho odporu, metodiky je mo\u017en\u00e9 \u013eahko implementova\u0165 na vyu\u017eitie s mnoh\u00fdmi komer\u010dn\u00fdmi kryomagnetick\u00fdmi zariadeniami, v\u010d\u00edtane PPMS. Posledn\u00e1 zmienen\u00e1 mo\u017enos\u0165 roz\u0161iruje realiz\u00e1cie \u0161t\u00fadi\u00ed elektrick\u00e9ho odporu na teplotn\u00fd interval 0.3 K \u0336 300 K a magnetick\u00e9 polia do 9 Tesla.
