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 closed chamber principle of the VapoMeter ensures that the measurements and results are not affected by ambient airflows. Furthermore, the measurement principle allows measurements at all angles and at virtually all body sites. The Delfin VapoMeter offers many benefits for TEWL measurements.
Benefits of the VapoMeter:
- Unaffected by ambient airflows like breathing, air conditioning, etc.
- Orientation free measurements – can be used at any angle
- No saturation at high TEWL values
- Measurement time 7 – 12 seconds
Accurate measurement of transepidermal water loss (TEWL) is important for a wide range of clinical and personal care applications and for claims validation. The measurement of TEWL provides key information about the skin barrier function and skin condition. The skin barrier function is an important indicator of many skin conditions, making it a regularly studied topic in skin research and personal care R&D. The Delfin VapoMeter has been used in hundreds of studies related to the skin and there are a lot of reference publications available. By offering a range of adapters of different sizes, the VapoMeter is also fully applicable for in-vitro studies.
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

Conclusion
A Platform for Precision, Portability and Progress
TDC measurement is no longer just a research tool — it’s a clinically valuable, field-proven solution for objective edema assessment. With Delfin’s LymphScanner, healthcare providers gain access to real-time, actionable data that improves diagnostics, enhances therapy monitoring, and supports evidence-based care.
At the same time, medical researchers are leveraging the same technology to explore new frontiers in skin and soft tissue science — including breast edema, lower limb lymphedema, head and neck swelling, and midline edema.
Whether you're treating lymphedema or designing the next clinical study, Delfin's TDC devices empower you with precision you can trust — in the palm of your hand.
