To ensure the highest quality cryogenic measurement and control performance, the new Model RX-102B-CB can be used in combination with the Lake Shore Model 370 AC Resistance Bridge. Unique patented noise reduction features in the Model 370 allow trouble-free low‑noise ULT resistance measurements. The Model 370 can multiplex up to 16 channels, and for precise control of cryogenic temperatures comes equipped with an independent proportional-integral-derivative (PID) control loop with maximum heater output of 1 W.
