I really only got this to check on my water pH and the ORP levels, but dang is this a full package deal. Yeah Its a little more expensive than I was hoping to pay, but it is worth the price! Its an easy to use set up with some extra packets in the box for recalibration if needed at a later date. Its provided a lot of insight about the water quality over here and how my habits can improve the water Im drinking (Boil and filter!)

I have recently been drinking hydrogen water made from hydrogen water bottles. I thought this water tester would be a good way to test the water and make sure it working properly. The first time I used it it was a bit confusing to get it to the correct setting but once you figure out how to use it it is very easy to use. This seems to fairly accurate but if you take multiple tests of the same water it will end up showing you different results. The results aren't so far off that it doesn't seem accurate but it is something to consider. Overall I think this is a fairly good investment if you like drinking hydrogen water.

I started on making my own hydrogenated water as a health supplement. I use a canister that generates H2 in water. However, since there is no taste, there is no way to know the level of H2 in the water or even if the device actually works. The effectiveness of H2 therapy is dependent on the concentration of H2.This test meter shows the concentration of H2 in the water. The LCD displays H2 in different read-outs (I use PPM). It tells me if the cycle was effective by the level of H2 in the water, plus I can keep an accurate record of the amount of H2 I take daily.

I got this to test the hydrogen content of some of the hydrogen water bottles I have. So far, the readings seem fairly accurate but not perfect. I find that this works best with older style water bottles that produce larger hydrogen bubbles. Newer pressurized hydrogen bottles produce a lot of "nano bubbles", and it's my understanding that these meters can't accurately measure the nano bubbles.That being said, it seems to work relatively well. I tested 3 different devices and got readings ranging from 20 to 2000ppb hydrogen, which aligns with what I was expecting. Note that the readings on this cap out at around 2000ppb for hydrogen, and seem like they start losing accuracy as you near the upper end of this range.It works as good or better than I expected, but if you really want accurate hydrogen measurements, the H2 reagent drops are the way to go.

The ppm and ppb mode did not work it just shows a 0. The Ph and Orp worked as described.

I was unable to use this ..not sure how it’s testing H2 .. i returned it unopened . The box it comes it lists 8 different tests ( such as pH or ORP ) but doesn’t mention hydrogen .I suggest the manufacture rewrite their instructions

I wanted this for my pool to test the levels. It worked, but was a bit more of a pain than I wanted for this use. I'll probably go back to using the typical chemical test kit since this only tests the pH. But I knew this going into the order. I just thought it may be easier to use than one of the kits. It was, but to calibrate it you have to use some of the little packets. I wasn't all that crazy about that. In general, it worked, but isn't ideal for use with a pool.
