ABSTRACT:
An apparatus for testing skin moisture including a casing, a fixed base at the front end of the casing, at least one through hole on the fixed base, a hollow cylindrical metal electrode with a closed end passing through the through hole, and an electrically conductive elastic member in the electrode. The elastic member pressing between the electrode on a first end and is fixed to the casing at a second end. The casing has a correction resistor coupled in parallel with the elastic member. The correction resistor is coupled to a micro alternate current generator, and an alternate current resistance measuring circuit is coupled to a CPU single-chip microprocessor. A measured value of resistance is compared with a predetermined value stored in a memory by a CPU single-chip microprocessor, the result of the comparison is displayed by a display device.
