The skin constantly looses water in form of vapor (TEWL). Already minor lesions of the skin result in an increased TEWL. The TEWL can be directly measured with the tewameter^® probe which is applied on the skin. It consists of two pairs of sensors to measure the humidity and temperature gradients in two different spacings. Based on the resulting humidity and temperature gradients the TEWL is automatically calculated and shown.
