AstroAI digital tire gauge is a convenient, portable device for measuring tire pressure, offering a wide measurement range of up to 150 PSI. It provides fast and accurate readings with a 0.1 increment that resets automatically and can be used for cars, trucks, motorcycles, and bicycles. Equipped with a backlit LCD display, it ensures easy reading even in low-light conditions. A practical button allows switching between different measurement units, including PSI, bar, kPa, and kg/cm². The auto shut-off function after 30 seconds of inactivity helps extend battery life. It operates on three LR44 batteries within a temperature range of 23°F to 122°F. Its ergonomic and durable design ensures a secure grip, while the nozzle easily forms a tight seal with the valve stem.
