A moisture content tester for non-destructive multipurpose testing that may be arranged in a drying apparatus or a testing box for proceeding a test of moisture content for an object to be tested and further have setting function for instructable water-containing rate is comprised of shell body, circuit plate, temperature compensation temperature-sensing bar, emitting pole, receiving pole, and controlling unit. A high frequency is emitted from the emitting pole and received by the receiving pole. Again, the received high frequency (sawtooth waveform) signal is transferred to the controlling unit through the circuit plate. The controlling unit then calculates the value of moisture content according to the received high frequency signal and the temperature value measured by the temperature compensation temperature-sensing bar. Further, the drying motion or displayed water-containing rate of the drying apparatus is controlled according to the value of moisture content.
