Description: 01. TPMS USB line charge, built-in lithium battery solar panel to help charge to extend the working hours of the display, 6* replaceable battery external sensor, can be switched to 4* sensor during use. 02. Accurating real-time monitoring of tire preure and temperature, four-wheel data.03. Keeping the tires balanced to prevent car accidents, save fuel, reduce wear and extend tire life.04. The display has three adjustable brightne to adapt to different environments.05. Built-in high temperature explosion-proof lithium battery, fast charging, long lasting power06. PSI, BAR two preure unit selection, C and F two temperature unit selection07. The sensor has been accurately matched to each tire position before leaving the factory.08.TPMS dedicated wirele radio frequency technology, real-time sensor update data, rapid alarm and splash screen when tire preure and temperature are abnormal09. TPMS dedicated Freescale chip solution, six in one, the signal is more stable and reliable, the monitoring data is more accurate10.DIY replaces the sensor battery. If you replace the newly purchased sensor, you need to re-match the receiving signal with the display.
