Abstract
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.Keywords
