TPMS for car /Tire Pressure Monitoring System for Car

Monitor car tire's pressure and temperature in real time.
Automatic sound and flash alarm six seconds after abnormal phenomenon appears, such as too high or too low tire's pressure or leakage.
Automatic sound and flash alarm six seconds after tire’s temperature becomes too high (exceed 75°C).
Temperature Measure Precision:±3°C
The waterproof and dustproof sensor can be used under awful condition.
The tire's pressure monitoring criterion can be customized.
The sensor's battery can be replaced freely. The normal life-span of battery is 1 years. When the capacity remained is insufficient, automatic sound and flash alarm shall remind user to replace the battery in time. (Battery Model No.: CR1632)
Pressure measurement range: 0-72.5psi
Pressure Measure Precision: ±1.45psi
Sensor is designed as a separate fitting. It can be fixed on the valve, no needing to disassembly the tire when mounting it.
User can learn to displace the sensor easily, no needing to mount it in procedures.
Guard against theft and alarm system is available for sensor.
Suitable for passenger cars, can monitor four wheel-tires simultaneously.
Four options for pressure unit:Kpa, PSI, Bar and Kgf/ cm2
Portable wireless monitor handset is powered by inner lithium battery and car DC power supply (12~24V) connection as well.
Please recharge the monitor's lithium battery by connecting the car DC power supply (12~24V) as soon as the voltage indicates too low.
Sensors' operating temperature:-10°C~85°C, that of receiver and monitor:-20°C~60°C
Monitor can be portable or be fixed on bracket.
