Certifications and Test Reports
Who has tested the H2CAP PLUS, what they measured, and the patents and product certifications behind it — back to the main hydrogen water bottle page.
Who has tested this, and how
Japan Hydrogen Water Promotion Association
JHPA, an industry association based in Osaka, tested the H2CAP in October 2018. Mineral water was filled to 90% of the bottle and measured immediately after a 3:30 cycle, using a Trustlex ENH-1000 dissolved hydrogen meter.
JHPA's qualification threshold is 300 ppb immediately after generation. The H2CAP measured more than three times that.
IonFarms R&D institute
IonFarms operates a corporate research institute formally recognized under Korea’s national R&D certification program, administered by KOITA (Korea Industrial Technology Association). This is where the current specification figures — 1,000–1,500 ppb dissolved hydrogen, −400 to −800 mV ORP — are measured.
- Dissolved hydrogen Trustlex ENH-2000, ±5 ppb
- ORP WTW MultiLab Pro 40 IDS
The ENH-2000 is the meter cited by name in published molecular hydrogen research. The MultiLab Pro 40 IDS is a benchtop instrument built for regulated laboratory environments (GxP, 21 CFR Part 11).

IonFarms holds 12 registered patents across its water electrolysis technology. Only two cover the H2CAP PLUS portable hydrogen generator specifically — the rest cover the company’s separate water ionizer product line. We list all 12 so nothing is implied that isn’t true.
