High-Precision Embryant Digital PH Meter: 0.01 Pocket Water Quality Tester

MikeMike: I have never owned a PH meter before, so I don't have any way to rigorously compare accuracy, however according to google, distilled water has a PH of around 5.4 to 5.7, this meter shows around 5.70 when I tested it in distilled water, so it seems accurate enough for my purposes - which are creating plant fertigation mixtures. The only thing I wasn't 100% sure about was if I'm supposed to dry the probe at all before storing it, the instructions say specifically not to touch the probe (make sense). So I have just been swirling it in distilled water and then replacing the cap while the unit is still a bit wet. Hopefully, that doesn't cause any issues, because I would like to continue using this instrument for a long time.

Tom: Digital ph meter I got this for my fish tank so I could test my water to make sure my tank ph level wouldn’t get too high it been very accurate and very easy to use I love knowing that my fish are safe highly recommended

Daniel C.Daniel C.: I'm a scientist for a living; so I've had some experience with expensive pH meters in the lab. I bought this little unit to test the pH of my spa, as the test strips were giving me a funky reading.

This unit is similar in concept to the larger lab units with a probe. If you calibrate the unit with the included buffers, according to the included instructions, it will give an accurate reading. I used positive controls of orange juice (acid) and our tap water (alkaline) and both readings were in line with my expectation. However, you have to give the meter a lot of time to reach its true reading. Submerge the probe for a good minute or two and let it stabilize.

Only downside is the buffers themselves. I wish we were told what the ingredients are (for purposes of safe disposal), and also that there were several packages instead of just one per pH.

Sarah B.: Numbers jump around a lot even when not in water, but overall easy to use and gets the job done after some time. Reading is good enough for my purposes.

Tyler: The pH meter is nice and simple, however, if the meter doesn't work with accuracy it is useless. I tried to calibrate the pH meter with the dry packets that are given as pH buffers when placed in water and used for calibration. This is a disappointing purchase and it may have just been odds were not in my favor.

Please send me a brand new meter and please make sure it is able to be calibrated before sending to myself (consumer).

Thank you,
Tyler Smith
