Model 346 Cryogenic Temperature Controller
Next-generation temperature controller – coming soon
The Model 346 cryogenic temperature controller is designed for rapid and precise temperature management. It features four 100 W heater outputs that deliver a total of 400 W of power, allowing the system to warm up twice as fast. It also includes four low-power 1 W heater outputs. With 10 standard inputs expandable up to 26 with option cards, the controller measures temperatures ranging from 300 mK to 1500 K.
Enhanced system control is achieved through two digital inputs for external triggering and two relays. The touchscreen interface ensures simple setup and monitoring, while the included ColdSync™ software facilitates advanced setup, initial configuration, and comprehensive data monitoring.
Model 346 features
- 400 W total heater power
- 300 mK to 1500 K temperature range
- 10 sensor inputs—expandable to 26 inputs with option cards
ColdSync™ software
ColdSync software, included with the measurement instrument, is designed to streamline the process of setting up new sensors and collecting data.



PANELS
The front panel of the Model 346 features a user-friendly touchscreen interface designed for basic control and monitoring. It allows easy toggling between different display modes.

Additionally, the front panel provides real-time error notifications, such as broken leads, allowing for prompt troubleshooting. Custom naming of inputs is also supported to help organize the setup. For advanced functionalities, the accompanying ColdSync software offers comprehensive tools for loading curves, data collection, setting up zones, and more complex configurations.
