Description
Riber JBA 12A Vacuum Pressure Gauge Controller Ionization Rackmount
The Riber JBA 12A (labeled "Alimentation de Jauge" — French for "Gauge Power Supply") is a rackmount ionization vacuum gauge controller designed to power and read ionization gauge tubes in high-vacuum and ultra-high-vacuum systems. It provides regulated filament and high-voltage emission control for the ionization gauge, with the resulting ion current displayed on the front-panel analog meter calibrated in Torr on a logarithmic scale. Units of this type were standard instruments in thin-film deposition, sputtering, and molecular beam epitaxy (MBE) environments where continuous vacuum monitoring is essential to process control.

Applications
Ionization gauge controllers like the Riber JBA 12A are used in vacuum systems that require measurement and monitoring of high-vacuum and ultra-high-vacuum conditions, typically in the range of 10⁻⁴ to 10⁻¹¹ Torr. They are found in sputtering deposition chambers, MBE (molecular beam epitaxy) growth systems, PVD (physical vapor deposition) coaters, e-beam evaporators, and electron microscope columns — any environment where process performance depends on knowing the precise base pressure. Riber is a French manufacturer historically associated with MBE and semiconductor epitaxy equipment, and gauge controllers of this type were typically rack-integrated into larger vacuum system control consoles. Replacement parts, servicing of legacy Riber systems, or reuse of the chassis for a compatible ionization gauge head are the most common reasons buyers seek units like this today.
This Riber JBA 12A Vacuum Pressure Gauge Controller is being sold as-is for parts or repair. When powered, the unit does come on and the analog pressure needle responds, but the power indicator light does not illuminate. We were not able to fully test the gauge controller at our facility, so functionality beyond what is noted here cannot be confirmed. The unit is being offered strictly in its current state with no guarantee of full functionality. The chassis shows the general surface wear and minor scuffing typical of rack-mounted lab equipment that has seen regular use. Please review our photo set carefully and contact us if you have any questions before purchasing.
