The Delfin VapoMeter has many important benefits for transepidermal water loss (TEWL) measurements. The VapoMeter is extremely practical and fast to use, and it operates with the closed-chamber measurement principle, which eliminates several environmental factors from the measurement. The VapoMeter’s hand-held portable design and wireless capability makes it extremely simple to use in a range of clinical and research applications.

The core of the VapoMeter is a sensitive humidity sensor in a cylindrical measurement chamber. The chamber is closed by the measurement surface, with the result that measurements are not affected by ambient airflows. The closed chamber measurement principle also allows measurements at all angles and at virtually all body sites. The Delfin VapoMeter has been used in large number of studies related to the skin barrier function and there are a lot of reference publications available. By offering a range of adapters of different sizes, the VapoMeter is fully applicable for in-vitro studies.

Accurate measurement of transepidermal water loss (TEWL) is important for a wide range of clinical and personal care applications and for claims validations. The measurement of TEWL provides key information about the skin’s condition and skin barrier function. The skin barrier function is an important indicator of many skin conditions and one of the most studied topics by cosmetic companies.

The VapoMeter has been used in a wide range of applications:

Skin barrier function
Efficacy testing
Skin irritation
Hyperhidrosis
Wound healing
In vitro studies
Veterinary studies
