Model 325 Cryogenic Temperature Controller
The Model 325 dual-channel cryogenic temperature controller is capable of supporting nearly any diode, RTD, or thermocouple temperature sensor. Two independent PID control loops with heater outputs of 25 W and 2 W are configured to drive either a 50 Ω or 25 Ω load for optimal cryocooler control flexibility. Designed with ease of use, functionality, and value in mind, the Model 325 is ideal for general-purpose laboratory and industrial temperature measurement and control applications.
Model 325 features
- Operates down to 1.2 K with appropriate sensors
- Two sensor inputs
- Supports diode, RTD, and thermocouple sensors
- Sensor excitation current reversal eliminates thermal EMF errors for resistance sensors
- Two autotuning control loops: 25 W and 2 W maximum
- Control loop 2: variable DC voltage source from 0 to 10 V maximum
- IEEE-488 and RS-232C interfaces
