2-1/16 Cobalt Boost/Vac Gauge

The 2-1/16 Cobalt Boost/Vac Gauge from Autometer is a precision dual-range diagnostic instrument designed for engine performance monitoring in high-demand operational and automotive environments. This gauge serves professionals—mechanics, technicians, and vehicle operators—who require real-time boost and vacuum pressure data to optimize engine tuning, troubleshoot turbo and supercharger systems, and maintain peak reliability. Whether in tactical field operations, competitive motorsports, or mobile workshop settings, accurate boost/vacuum measurement is essential for diagnosing fuel mixture problems, detecting intake leaks, and validating turbo performance.

Built with Autometer's cobalt-finish dial and precision movement, the 2-1/16 Boost/Vac Gauge delivers dual-range capability: measuring both positive boost pressure (turbo/supercharger output) and negative vacuum (intake manifold) in a single compact unit. The 2-1/16-inch dial face provides clear, at-a-glance readability under demanding conditions, while the robust construction handles vibration and thermal cycling inherent to mobile platforms and engine bays. The gauge features a standard barbed or threaded port connection for direct manifold or fuel-rail integration, allowing technicians to isolate turbo system integrity, diagnose vacuum leaks, and validate wastegate function without removing engine covers.

This instrument benefits engine diagnosticians, mobile mechanics, performance tuners, and fleet maintenance personnel who operate in field or lab environments where speed and accuracy directly impact mission capability. The compact 4.9 x 4.5 x 5-inch form factor fits standard automotive gauge mounts, dashboard pods, and portable diagnostic kits, making it ideal for rapid deployment in both stationary and mobile setups. Installation requires only a simple barbed or threaded connection to the target vacuum or boost port; no complex calibration is needed once seated. This gauge excels in turbo diagnostics, carburetor tuning verification, and intake system leak detection across gasoline and diesel powerplants.
