What is the hydrogen reduction method?

This method is a measuring technique that detects the oxidation reduction potential (ORP) in a solution and converts the detected value into the dissolved hydrogen concentration value. Our company’s original analysis technology and special sensor make it easy to measure the hydrogen concentration, which used to be a difficult and costly task in the past. Take advantage of our product to expand your sales of highly reliable hydrogen water.

Important information

When water with a low ORP is measured, a high hydrogen concentration value may be displayed on the ENH-2000, even if this water does not contain hydrogen. Be sure to use the ENH-2000 for measuring the hydrogen concentration in hydrogen water.


This measuring instrument has been developed for measuring dissolved hydrogen in the hydrogen water produced by hydrogen water generators and hydrogen generation apparatuses. This product uses a special sensor. Do not use this instrument for hot water, alkaline ionized water, salt water, juice, tea, supplement diluted water, etc. If you use this product for liquids other than hydrogen water, the displayed measured value will not indicate the hydrogen concentration.
