Model 335 features

Operates down to 300 mK with appropriate NTC RTD sensors
Two sensor inputs
Two configurable PID control loops providing 50 W and 25 W or 75 W and 1 W
Autotuning automatically collects PID parameters
Automatically switch sensor inputs using zones to allow continuous measurement and control from 300 mK to 1505 K
Custom display set-up allows you to label each sensor input
USB and IEEE-488 interfaces
Supports diode, RTD, and thermocouple temperature sensors
Sensor excitation current reversal eliminates thermal EMF errors for resistance sensors
±10 V analog voltage output, alarms, and relays
Designed with the user and ease of use in mind, the Model 335 temperature controller 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—50 W and 25 W, or 75 W and 1 W. With that much heater power packed into an affordable half-rack sized instrument, the Model 335 gives you more power and control than ever.
