Transmitter Module, Receiver Module (Tire Pressure Monitoring System)

TPM-V104C combines the display with the receiver. With a built-in rechargeable lithium battery, it doesn't need to be connected to vehicle-mounted power supply and can be flexibly placed anywhere. Compared with TPM-V104, the module has no slow air leak function. In addition, its alarm settings have been changed: (1) Low pressure alarm threshold value of the front and rear axles is from 1.2Bar to 9.7Bar. (2) High pressure alarm threshold value of the front and rear axles is 1Bar higher than low pressure alarm threshold value, which can reach 13.7Bar.
