Products âº VapoMeter - TEWL and evaporation Practical and reliable TEWL, evaporation and permeability measurements The VapoMeter is the only fully portable instrument available for the measurement of TEWL (transepidermal water loss) values and evaporation rates.
A volt-ampere (VA) is the unit used for the apparent power in an electrical circuit, equal to the product of root-mean-square (RMS) voltage and RMS current. In direct current (DC) circuits, this product is equal to the real power (active power) in watts.ome devices, including uninterruptible power supplies (UPSs) , have ratings both for maximum volt-amperes and maximum watts. The VA rating is limited by the maximum permissible current, and the watt rating by the power-handling capacity of the device.
