Dongguan Saftire Automotive Safety Technology Co.,Ltd

Product name: Tirebull SF881-6 wireless tyre pressure monitoring rv tpms system   tpms valve tire pressure check tire pressure meter

Key features:

Each tire is installed with a high sensitivity sensor transmitter, the data of real-time tire pressure and temperature are able to be transmitted to the display wirelessly.
With audio-visual alarm prompt function, enables your to quickly know what has happened, such as tire air leakage, too high tire pressure, abnormal tire temperature.  

TPMS receiver communicated to dashboard via CAN-BUS  

With 2.8 inch color LCD screen, 6 bundled sensors.

With repeater,could receiver the far away singal.

Sensors bound on the wheel hub,non-replacing the original valve.
