Cryogenic temperature controllers
Model 372 features
- For dilution refrigerators (DRs) to be operated below 100 mK
- Ability to increase the number of measurement channels to a maximum of 16 with an optional 3726 scanner
- Powerful impedance measurement capabilities such as quadrature measurements
- Multiple PID controllable outputs with up to 10 W of heater power available
Model 350 features
- Ideal for use with He-3 systems and other ultra-low temperature refrigeration platforms down to 100 mK
- Optimized performance with Cernox® RTDs
- Patented low-noise input circuitry enables super-low excitation power for minimal self-heating and high-resolution measurement
- 4 independent control loops and a broad range of I/O configurations can eliminate the need for additional instrumentation
- 4 PID-controlled outputs: 75 W warm-up heater, 1 W sample heater, and 2 auxiliary 1 W ±10 V outputs
