YEWHICK 4-in-1 Hydrogen Water Tester
High Accuracy Electrodes
Utilizes a unique spear sensor with a new glass bulb design that increases the area of the glass bulb and prevents interference bubbles from being generated in the internal buffer, making measurements more reliable.
Easy to Convert
Adjust to the desired mode, insert the product into the solution, and quickly obtain accurate test values. Operation is straightforward.
Easy to Place
The tester has two fixed columns at the back so that it can be placed on the desktop and is challenging to slip off.
Easy to Carry
Pocket-sized design, very convenient to carry. Fits in your pocket or carry-on bag. Measure anywhere, anytime.
Easy to Calibration
This product utilizes a 3-point pH auto-calibration mode for more accurate measurements. The package contains 3 packets of pH calibration powder.
Accurate pH/ORP/H2 Meter for Hydrogen Water
Product Features About Yewhick Hydrogen Water Tester
pH Meter for Kombucha
Kombucha is processed at a pH of 2.5-3.5, ensuring that the starting pH for the first fermentation of kombucha is 4.5 or less. Whether you are making kombucha, beer, vinegar, water kefir, etc., these pH testers are an ideal tool for the home brewer.
Accurate H2 Test Pen
The measurement range is large and wide, so you can measure the various indicators of water according to your needs. All-round measurement of water quality, drinking good water boosts the body's metabolism and makes it healthier.
Ever so easy to calibrate
How to Calibrate the pH ?
1. Before calibration, prepare 3 beakers containing separately 250ml of pH 4.00/pH 6.86/pH 9.18 standard solution.
2. Rinse the electrode with clean distilled water and wipe it dry. Turn on the pH meter and adjust to pH mode.
3. Immerse the electrode into the pH6.86 buffer solution, wait for the value to stabilize, press "CAL" for 5s, and the screen will display "CAL", when pH6.86 flashes 3 times, the calibration of pH6.86 is finished.
4. Repeat the above steps to calibrate pH4.00 or pH9.18.

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.

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
