Description
CTI-Cryogenics 8042002G003 Temperature Indicator Controller w/ Sensor Cable
The CTI-Cryogenics 8042002G003 is a benchtop temperature indicator and controller designed for use with CTI-Cryogenics cryopump and cryostat systems. It displays cryogenic temperatures on a large analog meter calibrated in Kelvin (10–300 K range) and provides adjustable low and high set-point relay outputs for automated control or alarm functions. The unit was manufactured by CTI-Cryogenics of Waltham, Massachusetts — a Helix Company — and is a standard accessory for monitoring cold-head and cryopump temperatures in vacuum and cryogenic environments.

Applications
The CTI-Cryogenics 8042002G003 is used to monitor and control temperatures in cryogenic vacuum systems — most commonly with CTI-Cryogenics cryopumps (such as the Cryo-Torr and On-Board series) and closed-cycle refrigerator cold heads used in semiconductor processing, thin-film deposition, and research vacuum chambers. The controller reads the signal from a cryogenic temperature sensor (diode or resistive type) attached via the sensor cable, displays the temperature in Kelvin on the analog meter, and triggers relay outputs when the temperature crosses the user-set low or high thresholds. This type of controller is used in semiconductor fabs, university research labs, and industrial vacuum coating systems where precise cryogenic temperature monitoring is required for process control or equipment protection. CTI-Cryogenics equipment from this era remains widely used in legacy vacuum systems and is actively sought for maintenance and replacement applications.
This CTI-Cryogenics 8042002G003 Temperature Indicator Controller has been inspected and appears to be in good used condition. The front panel analog Kelvin meter face is intact and clean, and the front-panel buttons and controls are present. The enclosure shows general surface wear and light scuffing consistent with lab use. A calibration service sticker is visible on the front panel. The two-prong AC power cord shows some wear at the plug body. The unit includes the 10-ft sensor cable (P/N 8042026G001) with its multi-pin circular connectors intact; no cryogenic probe or sensor is included.
