Tire Preure Motorcycle Monitoring System with 2 External Sensors Motor TPMS Real-time Voice Alarm Tyre Security USB Charging Descriptions: Many motorcycle accidents are caused by the flat tire on the road. As a motorcycle owner, the safety of driving is the first thing. To reduce such accidents, the installation of tire preure monitoring system (TPMS) is neceary. With the TPMS, we can keep the tire working within the specified preure and temperature range at any time to reduce the damage of the tire for safe driving.Main features:- Powerful TPMS:TPMS can monitor tire preure / temperature status in real time, which will transmit real-time voice alarm and warning indicator light to remind the driver for driving safety.- Wide compatibility:This system is widely compatible with those motorcycles with 2 tires. You don't have to worry about the compatibility iue.- Power supply:Supports USB charging, which means that you could use the USB cable (not included) to charge it up while it is in low power, rather convenient.- 2 external sensors:Its 2 external sensors with IP67 waterproof grade are suitable for being used on rainy days. Besides, they are in high sensitivity and good accuracy for measuring preure and temperature.Specifications:External sensor:- Battery: built-in 140mAh button cell- Waterproof grade: IP67- Working temperature: -30 - 80 Deg.C- Storage temperature: -30 - 85 Deg.CTPMS:- Battery: built-in 345mAh Li-ion battery- Operating voltage: 3V- Working frequency: 2.4GHz- Response time: 6s- Working humidity: 95 percent and le- Preure monitoring range: 100 - 900 kPa- Preure accuracy: minus or plus 10 kPa Intelligent Solar TPMS Car Tire PreureWhen you receive the package and turn onthe receiver, the receiver displays "--" or "00", please don't worry.You only need to mount the sensor on the tire, wait for about 1 minute, and you will see the display shows the preure and temperature of the tire.-Solar power charging, don't need to charge by connecting car cigarette lighter-Colorful LCD Digital displaying, clear to show tire information-Rear-time monitoring preure & temperature of 4 tires-Low air preure/high temperature alarm-High Temperature / Leakage / Low Battery Alarm-Intelligent Shock Boot when car moving, don't need to turn on/off-Wirele connect by sensors, easy install-Build-in sensors and external sensors options, meets all your need-Freescale chip sensors and fit on almost 98% cars on market-Two units (PSI / Bar) changeable, you can set the one you like.External Sensor ( Option )- Easy to install, convenient to replace-Dust-Proof / Water-Proof / Anti-theft-Anti High Temperate and Cold-IP67 Protection / Waterproof-Working Temperature: -20-85-Battery Life: 2 Years,replaceable
