摘要：

A bridge circuit is described which provides an increase in signal/noise by a factor of 10-100 over previous designs frequently used to monitor very low temperature resistance thermometers. The four-terminal arrangement reads directly in ohms and requires that only the thermometer be located in the cryostat.
