The oxidation-reduction potential and the hydrogen molecule concentration in electrolyzed water generated by use of electrolytic apparatus LB-002 (Lita hydrogen dual bottle) with electrolysis of tap water for 30 minutes

	Oxidation-reduction potential (mV)	Hydrogen molecule concentration (μg/L)
Before electrolysis (tap water)	+267.0±3.3	0.3±0.4
After electrolysis
1	–283.8±20.9	579.0±30.6
2	–241.5±59.3	473.8±22.1
3	–219.5±38.3	389.0±11.0
4	–236.8±7.9	475.3±72.9
Mean±SD (all 16 samples of 1–4)	–245.4±43.9	479.3±79.1

Note: Data are expressed as the mean ± SD (n = 4). Four independent measurements were executed for each lot apparatus differently manufactured.
