Description

RMC Cryosystems CR31-42 Temperature Controller 120VAC IEEE RS-232 2 Analog Outputs

Benchtop cryogenic temperature controller for managing thermal conditions in cryostat systems. Operates on 120VAC and provides PID control with dual analog outputs via BNC connectors.

Specifications & What's Included

  • Model: CR31-42
  • Power: 120VAC
  • Control Type: PID
  • Interfaces: IEEE (GPIB) and RS-232
  • Analog Outputs: 2 (BNC connectors)
  • Sensor/Heater Connectors: D-Sub
  • Display: LCD
  • Includes attached power and signal cables

Applications

Used in laboratory and research environments for regulating cryogenic systems, liquid helium cooled equipment, and low-temperature experiments. The dual analog outputs allow simultaneous control of heating and cooling elements or monitoring of multiple temperature zones. GPIB and RS-232 interfaces enable remote operation and data logging in automated test setups.

Condition: Used
This RMC Cryosystems CR31-42 Temperature Controller has been inspected and is in good condition. The front panel LCD is functional and displays readings (visible in the photos showing K S1, K O1, K S2, and K O2 values), and the keypad and Power switch appear intact. The enclosure shows light surface wear and minor scuffing consistent with lab use, but there is no cracking or significant damage. The rear panel ports — IEEE (GPIB), RS-232, two BNC Analog Outputs, and the Sensors/Heaters D-Sub connector — all appear clean and undamaged. The internal Nidec Beta V cooling fan is present. Please view our photo set and contact us if you have any questions.
