What if a minus value does not appear in the oxidation redox potential (ORP)?
Occasionally, a minus ORP does not appear when measuring Kangen water with a commercial ORP meter. This is because an insufficiently cleaned electrode or dried electrode may cause the contamination to remain on it, and these electrodes must be cleaned with strong acidic water to perform accurate measurement. It is also because raw tap water contains various kinds of ions that can cause the ORP values to vary up to several hundred mV, depending on the quality of water. As a result, generated Kangen water may be affected by raw water to the extent that the contained carbonate ions provide a buffering action* that keeps the pH and ORP unchanged, even after the water is electrolyzed. Because it is water electrolysis, Kangen water can be confirmed not only by the ORP, but also by simply checking whether or not you can see hydrogen bubbles that should be visible in the Kangen water immediately after it is generated. (* Buffering action = Power to keep the condition as is.
