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.

Abstract: This invention discloses an apparatus for testing skin moisture, which comprises 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; wherein the elastic member is pressed into the electrode, the other end of the elastic member is fixed into the casing, and the casing has a correction resistor coupled in parallel with the elastic member, and 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. In the test, the electrodes are pressed onto the skin of the person taking the test, so that a resistance can be measured when a micro alternate current of the electrode passes through the skin.
