Abstract:
1. An apparatus for testing moisture in skin comprising: a) a casing having: b) a fixed base located at a front end of the casing and having of at least two through holes; c) at least two conductive electrodes, one of the at least two conductive electrodes is inserted into each of the plurality of through holes of the fixed base from an interior of the casing and protruding from the casing, each of the at least two conductive electrodes being movable between compressed and extended positions and having a flange limiting a length of outward movement in the extended position, the at least two conductive electrodes being connected in parallel to a correction resistor; and d) at least two elastic members, one of the at least two elastic members having a first end pressing outwardly against an interior of each of the at least two conductive electrodes and a second end connected to the micro alternate current generator and the alternate current resistance measuring circuit, wherein, when the electrodes engage the skin, the at least two elastic members providing a constant pressure between the skin and the at least two conductive electrodes, the CPU single-chip microprocessor receiving a measured result from the electrode least two electrodes and comparing the measured result with the predetermined value stored in memory and obtaining a compared result, and the display device displaying the compared result.
