1. There are 4 units for pressure measurement: 0-150PSI, 0-10Bar, 0-1000KPA, 0-10kg/cm². Press the on/off button to change the data unit. Only compatible with Schrader valve. 2. LED backlight and illuminated nozzle allow clear reading of data even at night or in dark environments when testing tire pressure. 3. Easy to use with one button. Press "ON/UNIT/OFF" to turn on the pressure gauge, select the desired unit, and connect it to the tire valve. The device automatically turns off after 30 seconds of use to save battery power. It is convenient to carry and can be placed in the center console or hung in the car. The ergonomic handle design and non-slip surface provide a comfortable grip. 4. Helps avoid difficulties at gas stations by allowing users to check their vehicle's tire pressure themselves. Maintaining normal tire pressure can reduce tire wear, extend tire life, improve fuel efficiency and vehicle operating performance, and help maintain safety while avoiding guesswork before continuing the journey. Suitable for passenger vehicles and motorcycles. 5. The digital tire pressure gauge can be used to measure pressure for cars, bicycles, balls, rubber boats and other products, offering a wide range of applications to support a safe journey. 6. Equipped with a blue backlit LCD display and illuminated nozzle, the digital tire pressure gauge ensures visibility in dimly lit areas and assists in adjusting the nozzle to the valve for a proper seal. 7. Features a digital display for clear and accurate readings with high precision in increments. The 4 measurement units are 0-150PSI / 0-10Bar / 0-10Kg/cm² / 0-1000KPA, reducing the need for guesswork compared to analog gauges. 8. One button with 3 functions: ON / UNIT / OFF. The non-slip texture and ergonomic grip make it easy to hold, and it automatically shuts down after 30 seconds to save energy. 9. To use, align the pressure tap with the tire valve, then press firmly to ensure an airtight seal. The tire pressure gauge will automatically display the reading. 10.
