Which temperature controller fits: 5 instruments for every level of need

Not sure which temperature controller is right for your setup? Start by asking yourself a few key questions to help narrow the options:

Doing dilution refrigerator work below 100 mK? 

Consider our Model 372 AC resistance bridge/temperature controller. It’s built for operation below 100 mK (when combined with our Rox™ temperature sensors) and makes it easy to perform multiple tasks that were once very difficult to perform reliably at ultra-low temperatures. This off-the-shelf solution for precision DR temperature control is backed by our decades of experience helping users succeed in this challenging environment.

Need ultra-low temperature control for He-3 platforms?

Look to our Model 350. It combines control down to 100 mK (sensor dependent) with four independent control loops and configurable I/O to manage the heaters and auxiliary devices typical of ULT refrigeration systems.

Need maximum heater power for complex or large cryogenic systems?

The Model 346 is the best candidate. Not only does it feature 10 sensor inputs (expandable to 26), but with four 100 W heater outputs (400 W total), it’s designed for rapid warm-up, which can enable faster turnaround and more experiment throughput. Spend less time waiting, more time measuring.

Need general-purpose multi-zone sensor control with strong control power?

Our Model 336 is the go-to in the midrange of capability. It pairs 4 standard sensor inputs (expandable to 8) with 150 W of heater power, making it a strong fit for multi-point experiments where you need both stability and practical ramping performance.

Need two-channel capability but still want deep cryogenic reach?

Our Model 335 is a controller for smaller or simpler systems where you need measurement control down to 300 mK (sensor dependent), but it also provides 75 W of heater power across two outputs (configurable as either 50 W + 25 W or 75 W + 1 W).
