Model 325 Cryogenic Temperature Controller

Model 325 features

• Operates down to 1.2 K
• 2 sensor inputs and 2 autotuning control loops: 25 W and 2 W maximum
• Supports diode, RTD, and thermocouple sensors

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.
