The Model 350 ultra-low cryogenic temperature controller is designed for the demands of pumped He-3 refrigerators and other ultra-low and low-temperature platforms. The Model 350 controller, matched with Lake Shore’s industry-leading Cernox® sensors, provides a cryogenic solution that’s demonstrably best-in-class.
The patented noise reduction input circuitry of the Model 350 is ideal for ultra-low temperature (ULT) applications down to 100 mK. When combined with precision Cernox sensors, the performance-optimized design allows as little as 10 nA of excitation current to be used, minimizing self-heating effects and ensuring the best possible measurement accuracy throughout the entire temperature range.
It has 4 input channels and 4 independent control outputs that are configurable to support a broad range of I/O requirements, including the heaters and auxiliary devices typical of ULT refrigeration systems, as well as other cryogenic sensor types like ruthenium oxide and platinum RTDs. Standard computer interfaces enable remote communications, control, and coordination with other systems. 3-year standard warranty.
