Motorcycle Tire Tyre Pressure Monitoring with 2 External Sensor TPMS Feature: High polymer lithium power supply, fast charging, long lasting power, 2 external sensors. Real-time high precision tire temperature and pressure, data of two wheels are displayed at the same time. Saving fuel, predicting air leakage, prolonging tire service life, balancing tire pressure and ensuring driving safety. PSI, BAR two pressure unit selection, °C and °F two temperature unit selection. Each sensor has a separate ID code. The tire position can be interchanged. The sensor has waterproof function, waterproof rating: IP5K4K. Advanced radio frequency technology, effective transmission distance of more than 80 meters. Real-time update of data, instant alarm when tire pressure and temperature are abnormal. High temperature resistance explosion-proof batteries, the monitoring data are more accurate and ensuring the safety of life.
