Overview
The Weston analog vacuum gauge is a panel-mounted pressure meter designed to measure vacuum in the 0–10 Torr range. Manufactured by Weston Instruments, a trusted producer of precision test meters and instrumentation, this analog gauge provides straightforward, reliable vacuum measurement for research, laboratory, and industrial vacuum applications. The meter reads absolute pressure directly on a calibrated dial face, eliminating the need for external power or digital displays.
Key Features
