Description

LakeShore 330 Autotuning Temperature Controller IEEE-488 GPIB Serial I/O

The LakeShore 330 is a two-channel autotuning temperature controller designed for precision cryogenic and low-temperature research applications. It features built-in PID autotuning, a SoftCal calibration function, dual LED readouts for Sample and Control temperatures, and a front-panel Heater % bargraph for real-time monitoring. The rear panel provides IEEE-488 (GPIB) and Serial I/O connectivity for computer-controlled operation in automated measurement systems.

Specifications & What's Included

  • Manufacturer: LakeShore (Lake Shore Cryotronics)
  • Model: 330 Autotuning Temperature Controller
  • Serial No.: 33601
  • Sensor Input: Two channels — Channel A and Channel B (multi-pin circular connectors, rear panel)
  • Heater Output: HI, LO, and GND binding posts on rear panel
  • Display: Dual red LED displays — Sample and Control readouts
  • Heater monitoring: Analog bargraph display (Heater %)
  • Control mode: PID with AutoTune function
  • Calibration: SoftCal front-panel calibration function
  • IEEE-488 GPIB interface: Full IEEE-488 capability — SH1 AH1 T5 L4 SR1 RL1 PP0 DC1 DT0 C0 E1
  • Serial I/O port: RJ-style connector on rear panel
  • AC power: 90–125V / 2.0A or 210–250V / 1.0A (fuse: 3AG)
  • Power connector: Standard IEC C14 inlet
  • Form factor: Benchtop
  • Unit only — no cables, sensor leads, or accessories included

Applications

The LakeShore 330 was designed for temperature measurement and control in cryogenic research environments, commonly used with liquid helium and liquid nitrogen cryostats, closed-cycle refrigerators, and low-temperature sample stages. It supports a range of resistive temperature sensors including silicon diodes, platinum RTDs, and thermocouples via its two independent input channels. The IEEE-488 GPIB interface made it a standard choice for integration into automated test systems and physics laboratory setups — particularly in university and national lab settings where computer-controlled temperature sweeps and data logging are routine. LakeShore Cryotronics temperature controllers from this era remain sought after for legacy cryogenic systems that were designed around them, as well as for general low-temperature PID control applications where the hardware is compatible.

Condition: For Parts or Not Working
This LakeShore 330 Autotuning Temperature Controller powers on but has a missing power button (the button cap is absent — the switch itself can still be actuated). Upon power-up, the unit displays error code ER27 on the Sample readout; no further functional testing was possible beyond confirming it powers on. It is being sold AS-IS for parts or repair and is not guaranteed functional. The rear panel, IEEE-488 GPIB connector, Serial I/O port, heater output binding posts, and Channel A and B sensor connectors all appear intact and show normal cosmetic wear consistent with lab use.
