DPD vs ORP vs Methylene: 3 methods, 1 truth

Paul Fournier

— WEEKLY EDITION · FRIDAY MAY 29 —

ORP is marketing. Methylene is approximate. DPD measures.

ORP (redox potential): measures an electrical tendency of water, not the H₂ concentration. ORP variation can come from Cl₂, O₂, H₂S — not only H₂. Pure marketing.

Methylene blue: sensitive colorimetric indicator (turns transparent in the presence of H₂). Accurate to ±15-20%. Good for quick test, insufficient for validation.

DPD (N,N-diethyl-p-phenylenediamine): H₂-specific reagent coupled with a calibrated photometer. Accurate to ±5%. It's the method of peer-reviewed studies.

The DPD kit delivered with ELITE 9K costs €11 — it's the most important part of the product.

±5% DPD · ±15-20% Methylene · Marketing ORP

« If someone sells you an ORP measurement, they're selling you marketing. Science requires DPD. »
