The AutoMeter Cobalt mechanical vacuum/boost gauge is a 2 1/16" instrument that reads -1 to +2 bar using a high-precision Bourdon tube movement. It requires only a 1/8" NPT pressure connection—no electrical hookup—and includes 1/8" NPT fittings plus a nylon line kit. Modern blue through-the-dial LEDs ensure visibility at night while the mechanical movement delivers accuracy and durability in demanding environments.
