Skin-pH-Meter PH 905

pH-Measurement on Skin and Scalp

The Skin-pH-Meter PH 905 is a quick, easy and economical tool to specifically measure the pH on the skin surface or the scalp.

  • Advantages of the Skin-pH-Meters

    • The modern, high quality electronics of the probe allow a very quick (1 s) and reliable measurement avoiding occlusion effects.
    • Continuous measurement over long-term periodes possible, e.g. for in-vitro applications.
    • The probe head is planar for measuring optimally on the skin surface.
    • Single and continuous measurement possible.
    • pH is expressed with one decimal.
    • Regular calibration can be done by the user.
    • Worldwide established instrument with a broad range of studies.

    The Skin-pH-Meter PH 905 is available as a stand-alone device, in the Derma Unit SSC 3, connectable to the MPA systems, or as a wireless probe (please see details in Basic Probe Systems).

  • The Measurement Principle

    pH electrode eThe measurement is based on a high quality combined electrode, where both, H+ ion sensitive electrode and additional reference electrode are placed in one housing. It is connected to a probe handle containing the measurement electronics.pH display in the software
  • Fields of Applications

    pH laboratory02

    There are many fields of application where changes in skin pH are of interest.

    • In pharmaceutical, cosmetic and household application fields for the development of specific products (skin care, hair care, detergents, pharmaceuticals, etc.) and claim support
    • Typical claims (examples) substantiated with the Skin-pH-Meter: pH-neutral, respects skin pH, for sensitive skin, protecting, restoring/repairing, balancing/normalizing, soothing, cleaning/purifying, anti-acne, anti-dandruff, anti-bacterial, anti-pollution, and many more
    • In dermatological basic research in humans and animals.
    • In occupational health to show the importance ofpH meter dog the application of skin protection products in certain work areas
