Skin Diagnostic SD 202

For every measurement the suitable device

  • The basic device measures skin hydration and oil (sebum) on skin and hair as well as melanin (pigmentation)/erythema (redness).
  • Configurations with other probes e.g. pH, skin temperature for the assessment of micro circulation or TEWL-index are optionally possible.
  • The display shows immediately the measurement.

skin hydration measurement, easy and quick anywhere on face and body
melanin & redness measurement - skin colour
measuring the barrier quality of the skin (TEWL-Index)
pH measurement on the skin
sebum measurement on skin, hair and scalp


Advantages of the SD 202

SD202
  • Battery-operated unit can easily be moved around and transported. Ask for a special transportation suitcase.
  • Flexible solution for all kind of measurements
  • They can be used easily on the counter, in a beauty or hairdressers institute, at the dermatologist or in the pharmacy to attract customers and to increase the sales of cosmetic products.
