MEASUREMENT PRINCIPLE
The VapoMeter is equipped with a closed cylindrical chamber that contains sensors
for relative humidity and temperature. The figure below shows a linear increase of
relative humidity (RH%) in the chamber shortly after placing the device in contact
with the skin. The TEWL is calculated from the increase in RH%. The chamber is
passively ventilated between measurements.
