Feature:1. Simultaneously monitor and display all the 4 tires' pressure or temperature.2. This system is widely suitable for vehicle with four tires and the maximum pressure of the tire is below 8 bar, such as a commercial car, for jeep, off-road vehicle, minibus, and sedan car, etc.3. The real-time data of tires will be sent to the DVD through USB port to remind the driver for the comfortableness of vehicle and driving safety.4. Provides four sensors, which are suitable for using in any type of weather. Besides, they are in high sensitivity and fine accuracy for measuring pressure and temperature.5. Alarm when pressure and temperature is not up to standard like flat tire, improve fuel efficiency, prolong tire lifespan, ensure driving safety.Specification:The Tire Pressure Monitor can simultaneously monitor and display all the 4 tires' pressure or temperature.
