Many tasks were once very difficult to perform reliably at very low temperatures, such as temperature measurement, automatic and manual temperature control, and device or sample impedance measurements. Now the Lake Shore Model 372 AC resistance bridge and temperature controller makes it easy to perform multiple low-temperature tasks. Featuring patented noise-rejection technology and designed for measuring below 100 mK, the instrument is suitable for use in cryogenic measurement and dilution or adiabatic demagnetization refrigerator applications. It features a dedicated input for continuous, ultra-low temperature control, three heater outputs, and full quadrature measurement capabilities for impedance characterization. Lake Shore Cryotronics
