Wide Range: This tire pressure gauge features a 300PSI range and highly accurate ANSI B40.7 2A measurements. It is compatible with most vehicles, including cars, trucks, SUVs, motorcycles, bikes, and other items with Schrader Valves. It also provides 4 pressure units to choose from, PSI, bar, kPa, kg/cm². | Clear Display: The tire gauge's large digital screen provides clear and accurate readings to 0.1 units. It instantly measures tire pressure and immediately displays the readings, no more guesswork | Leakage-Proof Design: AstroAI had lengthened the gauge’s nozzle for better connections. This, with the help of its bright built-in flashlight and updated brass valve, allows the gauge to seamlessly lock onto the tire valve to avoid any leakage and get the most accurate readings at night. | Smart Design: The battery compartment is designed to store the Presta-to-Schrader adapter, while the tip's bright color stands out. Its ergonomic design provides easy grip and handling. | Superior Materials: The included high-quality AAA batteries allow the tire pressure gauge to idle for a long time, ensuring its always ready to go when needed. This, coupled with its ABS plastic casing and durable brass valve, combine to create a long-lasting and reliable glove box tool. | Simply press "ON/UNIT/OFF" button to turn on the tool, select the range, and automatically shut off in 30-40 seconds to save the power or hold on the button to turn off.
