TPMS Solar Tire Pressure Monitoring System, Universal Wireless Tire Safty Monitor with 4 External Sensors( 0-3.5Bar/0-50Psi ), LCD Real-time Display Pressure & Temperature Alerts Ensure Safe Driving

Why U Need TPMS Ensure that the pressure and temperature of the tires are maintained within the standard range, reducing the probability of punctures, damage, and reducing fuel consumption and damage to vehicle components. Collecting tire pressure, temperature and other data in a driving or stationary state using a high-sensitivity micro wireless sensor device fixed in the tire of a car. Solar power display features low carbon and renewable advantages, enabling you to charge the device faster and greener. 6 ALARM MODES: fast leak alarm, slow leak alarm, high pressure alarm, high temperature alarm, sensor fault alarm and sensor battery low power alarm, ensure safe driving. [ Press any button will stop alarming ] Sensor Installation (FL--Front Left, FR--Front Right, RR--Rear Right, RL--Rear Left) 1. Unscrew the valve dustproof cap then screw on the hexagonal nut; 2. Screw on the sensor; 3. Reversely tighen up the hexagonal nut to the sensor with the spanner; 4. Check the air leak using soapy water. After the sensors are installed, When the driving speed is up to 9mph or 15kph, the display will update the data of tire pressure automatically.
