The ARB ARB601 Digital Tire Pressure Gauge is a specialized tool built for demanding users, particularly off-road enthusiasts and professionals who require more than just a measuring device. Its standout feature is its dual role as a pass-through inflator gauge. It connects between an air compressor hose and the tire valve, allowing the user to add air while simultaneously watching the real-time pressure reading on its backlit digital display, which shows increments of 0.5 PSI up to 200 PSI. This eliminates the guesswork and back-and-forth of inflating, checking, and adjusting. Built by ARB, a legendary name in off-road equipment, it features a robust construction with a braided steel hose and brass fittings designed to withstand harsh environments.
The gauge is highly accurate, rated within ±1 PSI between 25 and 75 PSI. It includes a bleeder valve for fine-tuning. The primary drawback is its premium cost, placing it in a different category than standard gauges. Additionally, when using the bleeder to lower pressure, the display does not dynamically update; the user must disconnect and reconnect to get a new reading, a minor inconvenience. Its size and design are optimized for a workshop or vehicle recovery kit rather than a daily driver's glovebox. For those who regularly air down for off-road trails and air back up for the highway, or for anyone who wants a shop-grade, versatile inflation tool, the ARB ARB601 is a top-tier, purpose-built solution.
