Built from stainless steel and quality brass, it connects to standard compressors and Schrader valves and includes Presta adapters plus valve tools for bikes and cars. The unit reads in multiple pressure units and is factory-calibrated to deliver readings within 1% accuracy across a broad 3–250 PSI range.\u003c\/p\u003e\n\n\u003ch3\u003eHow accurate is the AstroAI inflator for regular vehicle tires?\u003c\/h3\u003e\n\u003cp\u003eThe gauge is professionally calibrated to provide precise readings within about 1% of the actual tire pressure across its full range. That accuracy makes it suitable for passenger cars, trucks, SUVs, motorcycles, and light off-road vehicles where correct inflation is important for handling and wear.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range: 3–250 PSI (0.2–17.2 Bar, 20–1724 kPa, 0.2–17.5 kg\/cm²)\u003c\/li\u003e\n  \u003cli\u003eCalibration: factory-set for ~1% accuracy\u003c\/li\u003e\n  \u003cli\u003eDigital readout for quick, repeatable readings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use this with my air compressor and different valve types?\u003c\/h3\u003e\n\u003cp\u003eYes — the inflator accepts both 1\/4\" and 1\/2\" NPT compressor outputs, so it fits most workshop and portable compressors.
