KJLC® 2200A Series Ion Gauge Controller

Note KJLC no longer offers the KJLC 2200A Series Ion Gauge Controller. For a Bayard-Alpert ion gauge controller, suitable for either tabulated, nude, or metal body gauge tubes, please see the MGC-3000 Series Vacuum Gauge Controllers. For a Bayard-Alpert ion gauge with integrated display, thereby eliminating the need for a controller, please see the KJLC 354 Series.

A convenient, low-cost gauge controller for single Bayard-Alpert ion gauges, suitable for either tubulated or nude gauge tubes.


  • Front panel access to all operating functions, including four set points for system control
  • RS-232 interface
  • Adjustments for sensitivity and emission
  • Ability to measure pressure during the degas cycle
  • Includes 6' power cord, accessory connector kit, rackmounting ears, and instruction manual
  • NIST traceable calibration certificates available upon request.

NOTE: Ion gauge tube and cable must be ordered separately.
WARRANTY: We're so confident in the quality and performance of our 2200 Series controller that it comes with a standard 3-year warranty!

Differences between the 2200 & 2200A The 2200 and 2200A are identical in terms of form fit and function, except for 1 important change. The ion gauge plug on the back of the unit has changed from a male connector to female connectors. This means cables from the 2200 generation will not work with the 2200A. An adaptor is available (part number KJLIGCA) that will allow old style cables to interface with the 2200A.
