REAL-TIME DISPLAY TIRE PRESSURE/TEMPERATURE & 6 ALARM MODES：The wireless TPMS used advanced chip and a liquid crystal monitor, to monitor and display accurate tire pressure and temperature of 4 tires in real-time. With 6 alarm modes: Fast/slow leak alarm, low pressure alarm, high pressure alarm, high-temperature alarm, sensor fault alarm and sensor battery low power alarm(Press any button will stop alarming), most tire pressure problem included,ensure driving safety. Clear DIGITAL LCD SCREEN & Free Adjustable Angle：TPMS Screen Bright backlist and clear readings, Pressure unit are Bar/Psi, and temperature unit is ℃/℉. Our tire pressure sensors are suitable for the tire pressure range of 0-81Psi (0-5.6 Bar), so can be widely used in 4 tires vehicles such as: Cars, SUVs, MPVs, Pickups, etc. The tire pressure monitoring system supports multi angle rotation adjustment, so you can adjust the desired angle at any time freely and read the data easily. 4 EXTERNAL CAP SENSORS：The TPMS's sensors can be sealed against water, dust and snow. Gives you early warning of air leaks and other abnormal tire situations so corrective action can be taken and tire life can be extended. [If one of the sensors does not work properly after the first install, reinstall again and wait a short while, it will work then.] VIBRATION SENSING FUNCTION：Tpms is equipped with a vibration detection function, no need to manually turn it on and off when using it. After successfully installing the tire pressure monitoring system, when you start the engine, the tire pressure monitor will detect the vibration and start automatically. If the tpms sensor does not detect vibration, the display will automatically enter sleep mode to save power. SOLAR POWER & USB CHARGING：This Tire Pressure monitoring systems Support solar power charging and USB cable charging, ensuring the tire pressure monitor system work continually both sunny and rainy days. It does not occupy the car cigarette lighter socket.
