The Model 350 is a cryogenic temperature controller designed for ultra-low temperature applications down to 100 mK, optimized for use with Cernox™ RTDs and other cryogenic sensors. It features four standard sensor input channels and four PID-controlled outputs, including a 75 W warm-up heater, a 1 W sample heater, and two 1 W ±10 V auxiliary voltage outputs. The instrument supports field-installable option cards for additional sensor types, including thermocouples, capacitance sensors, and silicon diodes. It has a 435 mm × 89 mm × 368 mm rack-mount form factor, CE certification, and RoHS compliance. The controller offers Ethernet, USB, and IEEE-488 interfaces for remote control, an 8-line graphic LCD display, and automatic PID tuning with zone control for seamless temperature transitions. It operates within an ambient temperature range of 15 °C to 35 °C, requires 100 to 240 VAC power, and includes a 3-year standard warranty.
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.
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-optimize
This single instrument offers extraordinary capability and flexibility, often eliminating the need for additional instrumentation in a refrigeration control system. Its four input channels and four independent control outputs 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.
