Tire Pressure Monitoring System is a wireless RF sensing device designed to measure and display the tire pressure and temperature. Once installed in your vehicle， the system will automatically monitor tires in rear-time for pressure and temperature. When any tire's pressure or temperature appear abnormal， the system wil， in rear-time， transmit signals to activate an alarm to warn the driver of tire problem. TPMS can help you to avoid tire accidents due to tire failure， to reduce the fule consumption and to extend the tire life. <br> <br> <strong>Features:</strong> <br> 1.Match with professional internal sensors. <br> 2.Pressure range: 0~3.5Bar / 0~50PSI. <br> 3.Adjustable viewing angle of display. <br> 4.Military sensor battery : Long battery life (&gt;6 years). <br> 5.Sensor preset in factory， no pairing is needed. <br> 6.Wireless transmission， no wires connection is needed. <br> 7.Display showing all four tires pressure &amp; temperature. <br> 8.Self-testing for each power on. <br> 9.End users can set the threshold of tire pressure &amp; temperature. <br> 10.Convertible pressure &amp; temperature unit (PSI / Bar， ℃ / ℉). <br> 11.Visual and audible warning. <br> 12.Sensor with wide range of operating temperature.(-40℃~+125℃/-40℉~+257℉) <br> <br> <strong>Specifications:</strong> <br> Brand: Steelmate <br> Model: TP-03 <br> Operating Voltage: 2.0 ~ 3.8V <br> Operating current: ≤18mA <br> Package size: 23.5 * 18 * 7cm / 9.3 * 7 * 2.8in <br> Package weight: 458g / 16oz <br> <br> <strong>Package List:</strong> <br> 1 * TPMS Display <br> 4 * Sensors <br> 1 * User Manual
