The Tewameter® TM Nano offers all advantages of the "open chamber measurement" and has additional benefits: 

• The ultra-small probe head (only 2 mm Ø) allows accurate and quick measurement of the TEWL in g/h/m² (pressure, occlusion, temperature). The small measurement chambers minimize the air turbulences inside the probe.
• 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 ideally suitable to measure on small sites, e.g. nails, lips, scalp with hair, hairy or 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.
• New sensor technology for precise and very stable measurements.
• The accurate calibration of the probe can easily be verified with the check calibration mode.

The Tewameter® TM Nano can be connected to the MPA-systems.
