Coming Soon… Next-generation Temperature Controller

400 W of control power with measurements down to 300 mK

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.

ColdSync™ software

ColdSync software, included with the measurement instrument, is designed to streamline the process of setting up new sensors and collecting data.

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

400 W heater power	Measure 300 mK to 1500 K	System control
System warm-up twice as fast	RTD – diode – thermocouple	USB, Ethernet, GPIB (optional)
Four 100 W heater outputs	Includes 10 inputs	Two relays for process control
Four 1 W heater outputs	Up to 26 inputs with option cards	Two digital inputs for external triggering

Option cards

The Model 346 features four option card slots for sensor inputs, along with an additional slot for GPIB communication. Adding an option card does not occupy any existing inputs.

RTD/diode option card

Each option card increases the number of inputs by four. With four option card slots and 10 existing inputs, the total can be expanded to up to 26 inputs.

Thermocouple option card

Add thermocouple measurement capability for temperature readings up to 1500 K.

GPIB option card

Add GPIB communication via a dedicated option card slot, separate from the four slots designated for sensor inputs.

346 front panel

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 organise the setup. For advanced functionalities, the accompanying ColdSync software offers comprehensive tools for loading curves, data collection, setting up zones, and more complex configurations.
