Skin-pH-Meter PH 905

• The Measuring Principle

  The measurement is based on a high quality combined electrode, where both glass H+ ion sensitive electrode and additional reference electrode are placed in one housing. It is connected to a probe handle containing the measurement electronics.

  

• Advantages of the Skin-pH-Meter

  • 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).

  

  

  

• Fields of Application

  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 of pH meter dog the application of skin protection products in certain work areas

   

  The Skin-pH-meter PH 905 is available as a stand-alone device.
