Skin-Colorimeter CL 400
An Economical Way To Look At Skin Colour
The Colorimeter CL 400 measures specifically the colour of the skin. Measuring values are expressed as coordinates in the colour space L*a*b* (or as RGB).
The Measuring Principle
The probe sends out white LED light, arranged circularly to uniformly illuminate the skin. The emitted light is scattered in all directions, some parts travel through the layers and some is scattered out of the Colorimeter principle skin. The light reflected from the skin is measured in the probe. The raw data of the probe are corrected with a special colour matrix to adapt them closely to standard values and are expressed accordingly.
Advantages of the Skin-Colorimeter
Fields of Application
The probe has been developed especially for the needs of measuring changes in the skin color.
Cosmetic and pharmaceutical efficacy tests, like sun screen products, self tanners, make-ups, whitening products, decorative cosmetics and carotene food supplements.
The Skin-Colorimeter CL 400 probe is available as a stand-alone device or connectable to the MPA systems or as a wireless probe.
