TPMS Tire Preure Monitoring System Wirele Solar Power RV Truck TPMS With 6 Sensors For Car Tow Motorhome Travel TrailersFeatures1. Solar & USB charging: Smart wirele TPMS with 2 charging methods ensures that the tire preure monitoring system continues to work, and the rechargeable lithium battery can extend the life of the tire. Solar and USB charging say goodbye to traditional wiring 2. Applicable to 6 tires: The trailer TPMS can simultaneously monitor the temperature and preure of 6 tires in real time with high precision, and can automatically change the corresponding data. The LCD display mode ensures high resolution and high definition definition.3. Accurate sensor connection: The wirele solar TPMS adopts American imported chip design, and the signal transmiion is more stable and accurate. Lightweight sensor design, easy to install. Support tire rotation function. IP5K4K sensor waterproof rating can avoid all kinds of harsh weather4. Balance tire preure: The tire preure monitoring system supports fuel saving, air leakage prediction and tire wear reduction, balance tire preure, and ensure driving safety. Equipped with radio frequency wirele technology, it can automatically alarm when tire preure and temperature are abnormal. Predict changes in tire preure by observing changes in tire temperature to avoid danger5. Unit switching: The tire preure temperature monitoring system has two preure units "PSI, BAR" and two temperature units ", " to choose from. When the value of one of the sensors cannot be displayed for the first time, please turn it off Lower the sensor to re-match or start the car meter ParameterReceiving frequency: 433.92MHzPower supply: solar powered, USB powered, built-in batteryWorking voltage: DC-5V inputBattery capacity: 500mAhPreure unit: bar / psiTemperature unit: / Working temperature: -20 - 85Storage temperature: -40 - 125ParameterTransmitting frequency: 433.92MHzPreure range: 0 8 bar / 0 116 psiDefault low preure alarm value: 1.8 barDefault high preure alarm value: 3.0 barPreure accuracy: 0.1 bar / 1.5 psiWorking voltage: DC+2.0 3.6VWorking temperature: -20 - 85Storage temperature: -40 - 125Waterproof level: IP67Battery: Built-in CR1632Button battery (removable and replaceable battery)Battery life: 1-2 years conventional Product List:Display x1Sensor x6Anti-theft nut x6Wrench x1USB cable x13M glue x2Manual x1
