- Model 350 Cryogenic Temperature Controller
The Model 350 is a cryogenic temperature controller for very low temperature platforms, including helium-3 systems, and works down to 100 mK. Its resistance inputs cover 0 Ω to 300 kΩ with excitation currents down to 10 nA. It is used to measure and control cryostat temperature.
- Model 336 Cryogenic Temperature Controller
The Model 336 is a cryogenic temperature controller with four sensor inputs and four PID controlled outputs, and it controls temperature down to 300 mK. It reads diode, RTD and thermocouple sensors, with scanner, thermocouple and capacitance option cards available for added inputs.
- Model 372 AC Resistance Bridge
The Model 372 is an AC resistance bridge and cryogenic temperature controller. It measures and controls temperature below 100 mK, reading resistance thermometers with an AC excitation rather than a DC one. It is used on dilution refrigerators and other very low temperature research platforms.
