2 W401 Tire Pressure Monitoring System


ORO-W401 Tire Pressure Monitoring Systems (TPMS), can monitor and provide tire
pressure, tire temperature and car battery information in real time to help the driver
control and keep the normal tire pressure in order to reduce the fuel consumption
and extend the tire life, and also through the battery information, the driver can change
the battery before any incident occurs and reduce the possibility of vehicle breakdown
on the roads.

ORO-W401 Tire Pressure Monitoring System, includes 4 tire sensors and 1 receiver
display, the TPMS can monitor the pressure/temperature by snap-in installation into
the tire, and transmit the tire information to the receiver by wireless. The TPMS
display will trigger an alarm when any abnormalities happen to the tire in order to
prevent any possible accidents which may happen to the driver/vehicle.
