Functional features 1.Solar energy automatic charging, lasting. 2.Simultaneous measurement of six tire pressures and tire temperatures, and simultaneous display of tire pressures and tire temperatures. 3.Built in high temperature resistant battery, long service life. 4.The lowest power consumption in the industry. 5.Use new sensors to monitor vehicle status without dead space. Solar Power & USB Charging The intelligent wireless system with 2 charging ways which ensure the tire pressure monitoring system will work continuously, rechargeable lithium battery to get electricity can increase the tires life. Solar and USB charging bid farewell to traditional wiring. Suitable for 4-6 tires Real-time monitoring the temperature and pressure with high degree accuracy for 4-6 tires simultaneously and can automatically change the corresponding data, LCD display mode ensure the high resolution ratio and guarantee the high-definition and no splash screen condition. Precise Sensor Connection The TPMS adopts USA imports chip design for better and more stable and accurate signal transmission. Light weight design for sensor for easy installation. Support tire position exchange function. IP5K4K Sensor waterproof grade can avoid various harsh climate. Balance Tire Pressure The system supports fuel-saving, air leakage forseeing and tire wearout reducing and balance tire pressure which will ensure safety driving. Equipped with RF wireless technology can auto-alarm when tire pressure and temperature is abnormal. With two pressure unit PSI,BAR "and two temperature unit ,"for option. Please unscrew the sensor to match again or start the car for meters when one of the sensors values cant be shown up at the first time. 100% Copper Guarantee It"'"s 100% Copper with great quality , it can support max 116psi / 8bar Installation is very simple Input Voltage:DC Displayer Parameter Working Temperature:(-20-80) Storage Temperature:(-30-85) Input Voltage:DC 5V Transmitting Frequency:433.92MHz Weight:104g5V Sensor Parameter Working Temperature:(-40-105) Storage Temperature:(-40-120) Pressure Range:0-116psi0-8bar Pressure Precision:1.5PSI0.1bar Temperature Precision:3 Transmitting Power:
