Lake Shore Cryotronics – Measurement and Control Technologies

Lake Shore Cryotronics, Inc. is an international leader in developing innovative measurement and control solutions. Their products include sensors for cryogenic temperature and magnetic measurements as well as systems for the magnetic and electronic characterization of materials.

Lake Shore Cryotronics – Measurement and Control Technologies

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:
