The Autometer Carbon Fiber II mechanical vacuum/boost gauge is a 66.7 mm instrument reading 30 in. Hg to 20 PSI that uses a patented Bourdon tube movement for high accuracy without electrical hookup. It includes 1/8 in NPT fittings and a nylon line kit for simple plumbing. Traditional perimeter incandescent lighting illuminates the dial for visibility, and the mechanical movement is specified for accuracy and durability in demanding conditions.
