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 toolow  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 receiver and LCD monitor is integrated as a whole in design.
The tire's pressure monitoring criterion can be customized.
The waterproof and dustproof sensor can be used under awful condition.
Normal life-span of sensor: over 7 years.
Pressure measurement range: 7.25-92.08psi.
Pressure Measure Precision: ±1.00psi.
Sensor is internal and need to open the tire when installing.
Suitable for passenger cars, can monitor four wheel simultaneously.
Four options for pressure unit: Kpa,PSI,Bar and Kgf/cm2
