16-channel scanner:

3726 16-channel scanner for the Model 372

The Lake Shore Model 3726 scanner is designed to connect 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.

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
