Transepidermal water loss (TEWL) is a key indicator of the skin barrier function and the ability to measure this accurately is essential in a wide range of clinical and personal care applications.

The VapoMeter is wireless, fully portable and measurements are unaffected by the instrument’s orientation. Measurements take just a few seconds and accurate repeatable results are obtained at both high and low evaporation levels. A range of Franz cell adapters are available for in-vitro studies.
