摘要：A system for measuring very low electrical potentials in a medium comprises anelectrode (550) having a low electrical impedance to the medium, a connecting element(552,553) made of a conducting material attached to the electrode (550), and an amplifier(520) including a low noise preamplifier attached to the connecting element (553). The
amplifier (520) contains an input bias circuit that minimizes the current drawn from theelectrode (550) through the amplifier inputs in order to minimize electrochemicalreactions at the electrode (550).
