Tiny TEWL meter

With its ultra-small measuring chamber (only 2 mm Ø), the Tewameter TM Nano from Courage+Khazaka measures the Transepidermal Waterloss (TEWL) in g/h/m² on small, or difficult to reach sites.

The measurement of the Tewameter is the basic measurement for all cosmetic applications regarding efficacy/safety testing and claim support. The Tewameter TM Nano is ideal for measuring on nails, lips, scalp with parted hair, small animals, etc.

Special rubber rings make the probe sit tightly even on slightly curved surfaces (e.g. the nails). As they are exchangeable, the rings can be cleansed hygienically.
