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.

ColdSync software
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.
