ACCURATE MEASUREMENTS: This heavy duty tire pressure gauge with inflator is manually calibrated to ANSI B40.7 Grade 2A (± 1PSI). It can freely switch between 4 pressure units: PSI, BAR, KPA, and KG/CM².

COMPACT & PORTABLE: Weighing less than a smartphone (0.65 lbs) this gauge is perfect for on-the-go pressure checks.

ALL-IN-ONE FUNCTIONS: The AstroAI T1 Digital Tire Pressure Gauge is compatible with standard 1/4” NPT air compressor accessories. It also includes an anti-air leakage connector, gauge, air hose, and deflation valve. This all-in-one unit allows for inflation, deflation, and tire pressure checks when connected to an air compressor.

ULTIMATE VERSATILITY: This gauge features a versatile 3-250PSI pressure range, which ensures accurate pressure measurement across all vehicle types including bicycles, motorcycles, passenger vehicles, and commercial trucks.

EXTENDED TEMPERATURE TOLERANCE: The AstroAI Tire Gauge maintains ±0.1 PSI accuracy across -14°F to 122°F (-10°C to 50°C), easily handling every measurement- even in extreme weather.

POWER-SAVING: Automatically turns on when it detects pressure above 10PSI, and turns off after 20 seconds of inactivity.
