Lake Shore Cryotronics, Inc., introduces the new Model 335 temperature controller. Designed with the user in mind, the Model 335 offers many user-configurable features and advanced functions that until now have been reserved for more expensive, high-end temperature controllers. The Model 335 is the first two-channel temperature controller available with user configurable heater outputs delivering a total of 75 W of low noise heater power. With that much power packed into an affordable half-rack sized instrument, the Model 335 gives you more power and control than ever.

Supporting diodes, resistance temperature detectors, and thermocouples, the Model 335 includes hardware and software features allowing you to easily control your experiments and automate processes. Output one functions as a current output while output two can be configured in current or voltage mode. With output two in voltage mode, it functions as a ±10 V analog output and still provides 1 W of heater power and full closed loop proportional-integral-derivative (PID) control. You can automatically calculate PID control parameters with improved autotuning, and alarms and relays help automate secondary control functions. The controller’s zone tuning feature allows you to measure and control temperatures seamlessly from 300 mK to over 1,500 K. This feature automatically switches temperature sensor inputs when your temperature range goes beyond the useable range of a given sensor. You’ll never again have to be concerned with temperature sensor over or under errors and measurement continuity issues.

The intuitive front panel layout and keypad logic, bright vacuum fluorescent display, and LED indicators enhance the user-friendly interface of the Model 335. Four display modes accommodate different instrument configurations and user preferences. Say goodbye to sticky notes and hand written labels, as the ability to custom label sensor inputs eliminates the guesswork in remembering or determining the location to which a sensor input is associated. These features, combined with USB and IEEE-488 interfaces and intuitive menu structure and logic
supports efficiency and ease of use.

Replacing the Model 331 and 332 temperature controllers, the Model 335 offers software emulation modes for drop-in compatibility. The commands you are accustomed to sending to the Model 331 and 332 are interpreted directly or translated to the most appropriate Model 335 setting. The Model 335 comes equipped with all of the functionality of the controllers it replaces, but offers additional features that save you time and money.
