The Televac® B2A Portable is a small, battery-powered, portable vacuum controller (also called a vacuum control unit, vacuum pressure controller, or digital vacuum gauge). It’s designed for use with Televac® 2A thermocouple gauges (Pirani). This vacuum pressure controller has a range of 1*10-3 Torr (1 micron) to 20 Torr (20,0000 microns) and an analog display (sweeping needle) that reads in microns (mTorr).
The portability of this vacuum controller makes it ideal for cryogenic and industrial gas applications where the vacuum controller needs to be carried to different (sometimes mobile) tanks to take vacuum measurements of their vacuum insulation or vacuum jacket. The B2A Portable has an analog display (sweeping needle), but if you’re looking for a portable vacuum controller with a digital display, we also have the VacuGuard™ portable vacuum controller.

While portable vacuum controllers are the best vacuum controller option for some applications, other applications are better suited for a rack/panel mountable vacuum controller or an active vacuum gauge where the electronics head is connected directly to the passive vacuum gauge (instead of with a cable).
If you’re interested in a rack/panel mounted vacuum controller, a good place to start is the MX200. If you’re interested in an active vacuum gauge, check out the MX4A for low vacuum measurement (10-3 to 1000 Torr) and the MX7B for high vacuum measurement (10-8 to 10-3 Torr).
