Abstract

The equipment monitors the product selected for appropriate skin care (scalp, face, hands, etc), and incorporates a measuring bridge comparing skin acidity with an electronic standard giving the mean value established in the laboratory representing a normal skin condition. The bridge can operate at high alternating frequency and low tension to avoid the effect of polarisation. The unit can be designed to allow automatic seeking of the point of balance by means of a servo-motor, and the information visualised may be recorded on a screen graduated in colours, so that selection of products used can be accurately effected.
