UIUZMAR Hydrogen Water Tester pH Meter 6 in 1 pH H2 ORP TDS EC Temp Tester Dissolved Hydrogen Tester for Hydrogen Water Bottle pH and ORP Meter for Household Drinking Water Hydroponics Pool

Im very satisfied with performance..

Bought a hydrogen water bottle. Used this to test it's validity. Works as advertised! Highly recommended.

H2 readings were all zeros after running H2 electrolysis. They gave me a replacement and it is working as described.

I recently purchased the Hydrogen Water Tester, and it's been an invaluable tool for monitoring my water quality! This 6-in-1 device measures pH, dissolved hydrogen, ORP, TDS, EC, and temperature, making it perfect for a variety of uses, from household drinking water to hydroponics and even pool maintenance. The readings are quick and accurate, giving me peace of mind about the water I’m consuming. It’s easy to use, and the clear display makes it simple to interpret the results. Having the ability to test for dissolved hydrogen is a unique feature that I really appreciate, especially for my hydrogen water bottle. Overall, this tester is a fantastic investment for anyone serious about maintaining optimal water quality. Highly recommend!

What I really like is that this one tester can test water for multiple characteristics. The product descriptions on the information page do a good job in describing this tester. I wanted this product specifically to test for hydrogen levels in water to make sure my hydrogen water generators were working properly. It definitely worked here and gave reading showing expected differences between tap water and water that was processed. The PH levels of the water could also be tested verify the hydrogen presence as the water was more alkaline after being processed. I also used this device to test the particles per million, PPM to confirm that my water filters were working properly when comparing the quality of the incoming and outgoing water.

STOPPED WORKING AFTER 5 MONTHS. I sell water ionizers and do a lot of demos. This wand was fantastic because it showed the pH, molecular hydrogen, ORP, and TDS. I recommended this one to many people on my team and for others to have in their homes. I even have this product on one of my Amazon lists! Over the course of five months, I have done the recalibration process 3-4 times. This morning, the wand will only read pH 4. (my pH drops are showing that the pH is likely to 9.0) Have set up to recalibrate with the designated packets. We can’t recalibrate to 7 or 11, because it will only read 4.0 in every calibration solution. I definitely used this wand a few times a month, and always stored it carefully. I’m disappointed, and share in case this review is helpful to anyone else.

unable to get an accuracy reading different from plain water after using a H2 bottle. Not sure if the meter is accurate or if the the H2 bottle is not working. At a loss on both products to see if they work.

Maxes out H at about 1.6 ppm.
