專利摘要：
A system for measuring polar substances includes a measurement module, a transfer module, a display module and a store module. The measurement module includes a measurement unit and a transmitter. The measurement unit measures the polar substances and produces a data-related signal. The transmitter transmits the data-related signal. The transfer module includes a receiver and a transmitter. The receiver receives the data-related signal. The transmitter of the transfer module receives the data-related signal from the receiver and transmits the data-related signal. The display module receives the data-related signal from the transmitter of the transfer module and shows the data-related signal. The store module receives the data-related signal from the transmitter of the transfer module and stores the data-related signal.
