Hydrogen Test Reagent，Dissolved Hydrogen Test Reagent ，H2Blue，Test the Concentration of Hydrogen Molecules in Water

This stuff works. Verified with a meter to check accuracy. Good for Hydrogen water bottle measurement.

I tested my HRW from a hydrogen bottle I purchased a couple weeks ago. I dropped 23 drops into the water and it still didn't remain blue. Looking at other reviews, I have to assume I have a great bottle. I am very pleased with knowing that my bottle is working. Now I just need to find out what 23 drops equates to in terms of hydrogen saturation. lol

I can't rate overall accuracy as I only had one Hydrogen Water Bottle to test, but tested against tap water. Still, it took 16 drops to turn to dark blue, where it only took 1 for reg tap, so I figure it has to at least confirm the unit I bought was worth it -- rated to be at 1400 +. Still, it was affordable, came on time and settled my worries about choice of Hydrogen Water Bottle. I'd buy it again and recommend it.

These drops only seem to measure up to 12000 ppb anything higher dosen’t seem to register

Worked perfectly

No stars, product a joke. One drop in water should turn clear, but did not, meaning there is no hydrogen in the water.

I used this reagent to test my hydrogen water, and it worked well. Compared to my PUR filtered tap water, it turned blue after just one drop. The video I attached shows water put through electrolysis with my hydrogen bottle—at the fourth drop, it turned blue, confirming the presence of hydrogen. It’s very easy to use: just fill the provided measuring cup with the dropper, add the reagent, mix, and count each drop that disappears—each drop represents about 100 ppb. While it’s not perfectly precise, it gives a good general idea of hydrogen concentration. One caution: the reagent stains easily, so make sure to set up a protected workspace before using.

It’s kind of hard to review this because I don’t really know the whole scientific make up of how it works but it does react with the water when you drop it in hydrogenated water. I have another review about the hydrogen bottle that I ordered and I go into way more detail about what this stuff is. Feel free to look at that review to get a better understanding or check out some YouTube videos that discuss a product very similar to this one.

Good
