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

Works well

This tests the PPM of the hydrogen bottles. It shows how much the hydrogen in the water. It's worth getting because the hydrogen companies lie about the PPM content!

just as advertised, no problems.

Don't know if it's my water bottle or drops It only took 3 drops to turn water blue I contacted water bottle company which stated it's a 2800 ppm bottle was told if I see bubbles the water has hydrogen I see.the bubbles but the tester tells me something else I they all said that this company of from China and that the test liquid expires after a month not to believe the date on box !! I will update review when I get the other tester.

The product does let me know there is molecular hydrogen present. It was nice to be able to see that one of my hydrogen water bottles had no hydrogen in the water, even though you could see the hydrogen bubbles bein produced. The second bottle did test positive for molecular hydrogen. However as far as counting the drops to determine the amount of hydrogen I would give the dropper 1 star. It is hard to control the drops and there are times it gives much larger drops resulting in an inaccurate assessment of the hydrogen concentration. I know there are dropper bottles that give an accurate drop as they are used in a number of ophthalmic products

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.

The instructions have so many typos and incorrect spellings that it’s impossible to understand. I have no idea if this works or not because I can’t make sense of the instructions. Clearly the person that wrote them does not understand English.

The media could not be loaded. 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.
