Zusammenfassung:	Instrumentation for the electrochemical noise measurement of chemical power sources is considered in this work. A high resolution NM-5 instrument based on a 32 bit “analog to digital” converter is tested with different objects—a passive resistor and RC-circuits as well as with several electrochemical systems—lithium batteries and hydrogen-air fuel cells. The possibility of low thermal noise measurement down to the level of 1 Ω by application of this instrument is shown.
