The Tewameter® is the most widely used instrument globally for measuring transepidermal water loss (TEWL) of skin. Designed, trademarked, and produced by Courage+Khazaka, the latest version of the probe is the Tewameter® TM Hex and is the successor of the Tewameter® TM 300.
In conjunction with the MPA CTplus software, it has become a powerful and useful tool to get deep insights into the skin barrier function. In addition to TEWL, it provides a few other crucial parameters such as local skin energy balance and water vapor concentration cH20 of the skin and ambience.
The Tewameter® TM Hex is an open-chamber probe i.e. it measures the density gradient of water evaporation from skin by means of temperature and humidity sensors placed inside the hollow cylinder of the probe. The open chamber measurement method enables continuous assessment of TEWL without influencing its micro environment.
The latest version of the Tewameter® is equipped with 30 pairs of temperature and relative humidity sensors, making it the most accurate TEWL measurement device. The sensors are arranged in 6 columns with 5 sensor pairs each, hence the name Hex. When compared to its predecessor, the upgraded model collects 15x the amount of information resulting in increased accuracy and repeatability.
Though the Tewameter® TM Hex covers almost all requirements, there are certain special applications that required Courage+Khazaka to develop special TEWL measurement probes. The following are the other probes in the Tewameter® family:
This is a TEWL probe with an exceptionally small open chamber having a diameter of 2 mm. This is particularly useful to evaluate the TEWL of inaccessible areas such as scalp, nails, lips, and so on.
