Frequently asked questions
What does TEWL-2 measure and which method does it use?
TEWL-2 measures transepidermal water loss using an unventilated chamber method. The manufacturer lists excised or in-vivo human and animal skin, and cultured skin. Operating conditions should match the selected method.
What range and measurement time are specified for TEWL-2?
The manufacturer table specifies 0–300.0 g/m²/hr and a measurement time of ≤15 s. The text also describes a result 7 seconds after equilibration. These timings have different conditions; account for both equilibration and measurement in the workflow.
How should the published accuracy and repeatability be read?
The manufacturer lists accuracy as 0.1 g/m²/hr and repeatability as 0.5 g/m²/hr, without a ± sign. These are different from range and should not be relabeled as resolution. Confirm test conditions and evaluation criteria for the application.
