Model 325 Cryogenic Temperature Controller

• 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

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 W or 25 W 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. More information on Model 325 Cryogenic Temperature Controller...
