Corneometer® CM 825
The World's Most Popular Skin Hydration Measurement Instrument
For more than 25 years the Corneometer® has provided the worldwide most used method to reproducibly and accurately determine the hydration level of the skin surface (Stratum corneum). This is documented by the numerous mentions in dermatology and cosmetology literature in which the terms "corneometry" and skin hydration measurements are inseparable. The accuracy of other hydration measurement instrumentation on the market is always assessed against the standard of the Corneometer®.
The Measuring Principle
The measurement is based on capacitance measurement of a dielectric medium. The Corneometer® CM 825 measures the change in the dielectric constant due to skin surface hydration changing the corneo capacitance of a precision capacitor. The measurement can detect even slight changes in the hydration level.

Field of Application
The hydration measurement is the basic measurement for all bio-medical and cosmetic applications.
The Corneometer® CM 825 is available as a stand-alone device, connectable to the MPA systems, as a wireless probe or in the Derma Unit SSC 3.
