Thus solving the general TPMS (tire pressure monitoring system) repeated charging, occupying the cigarette mouth, occupy a series of DVD display and other deficiencies! The composition of the solar TPMS is the same as that of the ordinary TPMS (tire pressure monitoring system), which is composed of a solar TFT screen receiving display and four pressure sensors / emitters. As the generous power generation panel long life, to provide at any time charging, so that the reception of the monitor power storage more robust and lasting; even in the absence of sunshine in the dark environment, rain and snow weather conditions can still serve more than 15 days, There are USB charger interface, dual charging system device to ensure that the machine really permanent life. External Internal Tire Pressure Monitoring System Motorcycle TPMS Real-time Tester LCD Screen with 2 External Sensors Descriptions: Many motorcycle accidents are caused by the flat tire on the road. As a motorcycle owner, the safety of driving is the first thing. To reduce such accidents, the installation of tire pressure monitoring system (TPMS) is necessary. With the TPMS, we can keep the tire working within the specified pressure and temperature range at any time to reduce the damage of the tire for safe driving.a Main features: - Powerful TPMS: TPMS can monitor tire pressure / temperature status in real time, which will transmit real-time voice alarm and warning indicator light to remind the driver for driving safety. - Wide compatibility: This system is widely compatible with those motorcycles with 2 tires. You don"'"t have to worry about the compatibility issue. - Power supply: Supports USB charging, which means that you could use the USB cable (not included) to charge it up while it is in low power, rather convenient. - 2 external sensors: Its 2 external sensors with IP67 waterproof grade are suitable for being used on rainy days. Besides, they are in high sensitivity and good accuracy for measuring pressure and temperature.
