Lake Shore 350 Cryogenic Temperature Controller

The Model 350 ultra-low cryogenic temperature controller is a powerful physics tool. Designed for the demands of pumped He-3 refrigerators and other ultra-low and low temperature platforms, the Model 350 provides excellent measurement performance, superior control accuracy, and convenient operation in a wide range of advanced research applications. Whether the need is for high accuracy with minimal thermal impact, or precise temperature control in high magnetic fields, or dependable measurement in radiation environments, the new Model 350 controller matched with Lake Shore's industry-leading Cernox® sensors provides a cryogenic solution that's demonstrably best-in-class.

Features:

• Ideal for use with He-3 systems and other ultra-low temperature refrigeration platforms down to 100 mK
• Optimised performance with Cernox® RTDs
• Patented low-noise input circuitry enables super low excitation power for minimal self-heating and high resolution measurement
• 4 independent control loops and a broad range of I/O configurations can eliminate need for additional instrumentation
• 4 PID-controlled outputs: 75W warm-up heater, 1W sample heater, and 2 auxiliary 1W ± 10V outputs
• Full 3 year standard warranty

The patented noise reduction input circuitry of the Model 350 is just one reason why this controller works so well for ultra-low temperature (ULT) applications, all the way down to 100 mK. When combined with precision Cernox sensors, this performance-optimised design allows as little as 10 nA of excitation current to be used, minimising self-heating effects, and ensures best possible measurement accuracy throughout the entire temperature range.
