Abstract
A self‐balancing conductance bridge is described that operates at sufficiently low power levels to be useful for thermometry at very low temperatures. It uses a four‐terminal configuration which largely eliminates the effect of lead resistance. Operation at a low frequency, synchronized with the 60 Hz power frequency, and the use of a wide dynamic range error detector make the bridge very insensitive to hum pickup and capacitive unbalance.Keywords
