Model 372 AC Resistance Bridge
Latest-generation design for ultra-low temperature applications
The Model 372 AC resistance bridge and temperature controller builds on the solid foundation provided by the original Lake Shore AC resistance bridge. The Model 372 provides the best possible temperature measurement and control capabilities for dilution refrigerators (DRs) that are intended to be operated below 100 mK. The Model 372 makes it easy to perform multiple tasks that were once very difficult to perform reliably at ultra-low temperatures:
- Temperature measurement
- Automatic or manual temperature control
- Device or sample impedance measurements

Scanners
The new Lake Shore Model 3726 scanner is designed for connecting to multiple ultra-low temperature measurement points in a system. With lower input noise and DC bias current, the 3726 scanner offers superior performance to the previous generation 3716 scanner and will be capable of taking full advantage of the performance improvements built into the Model 372.
The Lake Shore Model 3708 8-channel preamp/scanner offers an exceptionally low voltage noise floor specification of just 2 nV/√vHz, improving the utility of the Model 372 AC resistance bridge for ultra-low AC resistance measurements.
