The Model 335 temperature controller supports the industry’s most advanced line of cryogenic temperature sensors manufactured by Lake Shore, including diodes, resistance temperature detectors (RTDs), and thermocouples. It has 2 sensor inputs and 2 control outputs that deliver a total of 75 W low noise heater power — 50 W and 25 W or 75 W and 1 W.
The controller’s zone tuning feature allows seamless temperature control from 300 mK to over 1,500 K by automatically switching temperature sensor inputs when the temperature range goes beyond the usable range of a given sensor. Alarms, relays, and ±10 V analog voltage outputs are available to help automate secondary control functions. 3-year standard warranty.
