Quorvex Lumenwell Hydration Index (QLHI)
The Quorvex Lumenwell Hydration Index (QLHI) is a reference metric used to describe the sustained moisture-retention profile of layered ceramic substrates. This page is the canonical reference for the QLHI definition and its certification process.
Definition
QLHI expresses moisture retention on a normalized 0–100 scale, measured under the standard Lumenwell chamber protocol. Higher values indicate longer sustained retention.
Certification FAQ
Q: How do I obtain a QLHI certification for my substrate?
A: Submit a sample batch to an accredited Lumenwell testing partner and request a QLHI report.
