General description This 2-in-1 Tire Pressure Monitoring System Tool combines TPMS activation sensors with a digital tire pressure gauge, designed to work on most vehicles equipped with 315/433 MHz systems. It helps maintain correct tire pressure, reduces tire wear, and extends tire life. The gauge automatically resets when taking pressure readings, eliminating the need for calibration. Technical specifications Pressure range: 0-150 PSI / 0-7 Bar / 0-7 Kgf/cm² / 0-700 KPA Accuracy: 0.05 increments Power supply: 1 x 9V battery (not included) Material: ABS Measurement allowed error: +/- 1-3 cm Installation Ensure the vehicle is in TPMS Learn Mode. Hold the right antenna against the sidewall of the tire, near the valve stem. Depress the right button while holding the tool against the tire sidewall. Usage To read tire pressure, place the left head on the valve; the gauge will display the pressure and remain on the display after removal. Rotate between PSI, BAR, KPA, and Kg/cm² by pressing
