With its exceptional small measuring chamber (only 2 mm Ø), the Tewameter® TM Nano allows to measure the Transepidermal Water Loss (TEWL) in g/h/m² on small, or difficult to reach sites, e.g. nails, scalp with hair, lips, etc.
The Tewameter® TM Nano offers all advantages of the "open chamber measurement" and has additional benefits:
The Tewameter® TM Nano can be connected to the MPA-systems.

The open chamber measurement of the Tewameter® is the only method to assess the TEWL continuously, which is necessary for most applications without influencing the skin surface. Numerous studies are available.
