ABSTRACT:
A skin condition tester is disclosed employing an inexpensive, battery powered, I.C. comparator circuit that tests for dry, normal and oily skin. An instantaneous digital readout is obtained that may be converted into a light or a meter reading.
The circuit is lightweight and small, with no moving parts, and when used in conjunction with LEDs, provides virtually an instantaneous reading. The device is readily adapted to obtain a number of readings from an individual, without the necessity of dial adjustments.
