Our skin is the indispensable barrier of the body to the environment, thus essential for our health in many ways.

Measuring the Transepidermal Water Loss of the skin is a vital parameter to quantify the skin barrier function for various applications.



  • Small, easy to use, handheld Tewameter® with the world-wide most accepted “open chamber” technology, supported by thousands of publications, even used in space.
  • Ergonomic shape
  • suitable for right- and left-handed operators
  • 5 sensor pairs located in thewall of the probe head
  • Highly precise measurement value displayed in g/h/m2 (measurement uncertainty between the laboratory instruments TM 300 and TM Hex)
  • Super quick: 20 - 30 s measurement time
