AstroAI Digital Tire Pressure Gauge & Inflator 3–250 PSI, ±1% Accuracy — Locking Chuck & Bleed Valve

The AstroAI Digital Tire Pressure Gauge with Inflator is a portable, all-in-one gauge and inflator that reads 3–250 PSI with ±1% professional accuracy for cars, bikes, motorcycles and more.

If you want fast, reliable tire pressure checks and the ability to add or bleed air without multiple tools, this AstroAI unit combines a digital gauge, inflator hose, locking chuck and bleed valve in one compact device. Engineered with stainless steel and brass components, the tool attaches to standard Schrader valves and works with 1/4" NPT compressor fittings, making it a practical garage or roadside companion for everyday drivers and DIY mechanics.

How precise are the readings and which units does it support?

The gauge is factory-calibrated to deliver accuracy within ±1% across its full range, helping you trust each measurement. It displays pressure in four selectable units so you can match vehicle or equipment specifications.

• Measurement range: 3–250 PSI (0.2–17.2 Bar; 0.21–1724 kPa; 0.2–17.5 kg/cm²)
• Selectable units: PSI, kPa, Bar, kg/cm²
• Digital LED readout for clear visibility day or night

Can I both inflate and release air with this tool?

Yes — the AstroAI unit integrates an inflator hose and an air-bleed valve so you can add air from a compressor or let out excess pressure without swapping tools. The straight locking chuck secures to the valve stem to maintain a steady connection while you adjust pressure.

• Includes straight locking chuck and flexible hose for tight seals
• Built-in bleed valve for quick, controlled pressure reduction
• Compatible with standard 1/4" NPT compressor outputs and quick-connect fittings

Is this gauge rugged enough for regular use and travel?
