As a car owner, safe driving is the number one priority. In order to reduce the occurrence of such accidents, it is necessary to install a tire pressure monitoring system (TPMS). Through TPMS, we can make the tires work at any time within the specified pressure and temperature range to reduce tire damage and ensure safe driving.Fitment:The system is widely applicable to vehicles with 4 tires, the maximum pressure of the tires is 8.0 bar, such as commercial vehicles, jeeps, off-road vehicles, vans, cars, etc. with for Android displaysReceiverTransmission Frequency: 433.92MHzPower Supply: USB 5V / ACC 12V / OBD 12VOperating Voltage: DC 5V- 12V InputPressure Unit: Bar / PsiTemperature Unit: / Operating Temperature: -20-85 Storage Temperature: -40-125Internal SensorTransmission Frequency: 433.92MHzPressure Range: 0-8 Bar / 0-116 PsiLow Pressure Alarm Value: 1.8 BarHigh Pressure Alarm Value: 3.0 BarAccuracy of Measurement: 0.1 Bar / 1.5 PsiOperating Voltage: DC+2.0-3.6VOperating Temperature: -20-85 Storage Temperature: -40-125Waterproof: IP67Battery: Built-in CR2450 Button Battery(Can Not Removable and Replaceable)Battery Life: 2-3 Years .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Host4 x Sensor2 x Power Cable1 x OBD Power Supply1 x Sticker1 x Tape1 x ManualNotePlease note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
