A. Measurement Units: There are 4 units available: 0-150PSI, 0-10Bar, 0-1000KPA, 0-10kg/cm². Press the on/off button to change the data unit. Compatible with Schrader valve only. B. Illumination Features: Equipped with LED backlight and a lighted nozzle, allowing clear reading of data even at night or in dark environments when testing tire pressure. The blue backlit LCD display and illuminated nozzle ensure visibility in dimly lit areas and assist in adjusting the nozzle to the valve for a proper seal. C. Ease of Use: One button with 3 functions: ON/UNIT/OFF. Press the "ON/UNIT/OFF" button to turn on the pressure gauge, select the desired units, and then connect it to the tire valve. The non-slip texture and ergonomic grip make it easy to hold. After use, the device automatically turns off after 30 seconds to save battery power. It is very convenient to carry and can be placed in the center console or hung in the car. To use, align the pressure tap with the tire, then squeeze it firmly to maintain airtightness, and the tire pressure gauge will automatically display the reading. D. Functions and Applications: Helps avoid gas station frustrations by allowing self-check of vehicle tire pressure. Maintaining normal tire pressure may reduce tire wear, extend tire life, and contribute to improved fuel efficiency and vehicle operating performance, aiding in safety and reducing guesswork before continuing the journey. Suitable for passenger vehicles, motorcycles, bicycles, balls, rubber boats, and other products, providing a range of applications for daily use. E. Measurement Accuracy: Features a digital display for clear and accurate readings with high precision. The 4 units (0-150PSI / 0-10Bar / 0-10Kg/cm² / 0-1000KPA) reduce reliance on analog gauges. F. Notes: Due to differences in light and screen settings, the product color may slightly vary from the pictures. Manual measurement may result in slight size differences. Shipping quantity: 1 piece.
