PH Meter for Water Hydroponics Digital PH Tester Pen 0.01 High Accuracy Pocket Size with 0-14 PH Measurement Range for Household Drinking, Pool and Aquarium

Item came early, which is always good. Well packaged in a box, not just a bag. Easy to use. This one is my second in 3 years. Only thing...the box for a storage container was checked off as if it was provided, but there was none. I didn't care because I kept the one from my first one.

WORKS GREAT FOR THE MONEY

I use Aero-Grow, but needed a second meter, so I got this one. They look almost identical, and they calibrate exactly the same way. I used the same solution and calibrated them both at the same time. When I compared their reading in distilled water, this one measured a pH of 6.99, and the Areo-Gro 7.08.The only thing I liked more about the Areo-Gro, was:1. It was a lighted display, and2. Aero-Grow clearly says it is U.S.-made with domestic support.I’m giving this meter a 4 star only because I don’t know where it was made…and I think they should say so.

This is a piece of detritus. You know, the stuff the fish leave on the bottom of your tank. And I don't mean the food. It is actually worse than an off brand pH calibration solution I purchased. Amazon, you need to start carrying some quality products. I have been in the aquarium hobby since I was five. Started with a Trinidad guppy, a minnow and a 1 gallon Mason jar. I am 76 now and I have seen some trash over the years but these last two purchases were horrible. All I wanted was a pocket meter for a quick check. Followed the directions to calibrate. Carefully measured 250 ml of distilled water and mixed the powder until completely dissolved. Waited the five seconds and counted the 3 flashes and cleaned with distilled water, dried and moved to the next calibration solution. Went through all three. Just for kicks and giggles I put the meter in some water from my saltwater tank. The pH in it usually runs 8.1-803. Not with this thing. Nope, it was 4.6. I no longer trust the reviews because I don't know if I am even getting the same product. Evidently, there is a lack of quality control in the manufacture of the two items I purchased. This meter and an off brand calibration solution. By the way, I tried to use that solution to calibrate this meter after it failed using the powder than came with it. It was still so far off it is worthless. Between the two it was close to $50 wasted. Oh well.

Does the job. Accurate and easy to use.

I really didn't know. The numbers on the calibration solutions didn't get as high as the instructions directed to set the meter with..I guess it's close enough? Or the powders for the solutions were out of date?Beats me.

I bought this meter to measure pH on my expectant mare's milk to help predict her foaling window. I'm very impressed! It is much more accurate than testing strips for pools. There is none of the guesswork of trying to match the color on the test strip to the color on a chart. The meter measures exactly and accurately, from 0.00 to 14.00. Tonight measurement of her milk was 6.23 as opposed to looking at a color chart and trying to figure out what color orange the test strip matches. The meter was delivered on time, packaged well, and extremely reasonably priced. I highly, highly recommend!

So, I recently became the proud owner of a pH meter, and let me tell you, it's been one heck of a wild ride into the acidic and alkaline realms of liquid existence.First off, the moment I unboxed this thing, I felt like a mad scientist about to unravel the secrets of the universe – or at least the mysteries of my tap water. I dubbed it the "pH Master," and boy, does it take its job seriously.Testing various liquids became a bizarre adventure. I felt like a water detective, hunting down the elusive pH culprits in my kitchen. Spoiler alert: my tap water is apparently more mysterious than a Netflix crime series. Who knew H2O had such a dark side?Now, the real entertainment comes when you start testing random stuff. I found myself wondering, "What's the pH of my morning coffee? Is my plant's water too basic for its liking?" The pH Master turned me into a liquid Sherlock Holmes, solving the mysteries of pH, one drop at a time.But let's not forget the dramatic beeping – the pH Master's way of saying, "Hold on to your test tubes, we've got a pH anomaly!" It's like the soundtrack to a suspenseful movie, playing as I decipher the pH code of my surroundings.In conclusion, the pH meter has turned my ordinary water-drinking life into a thrilling comedy. Who knew checking the acidity of liquids could be this much fun? If you're ready to embark on a journey of liquid discovery and want your water to have a theme song, the pH Master is your ticket to a pHantastic time! 🎭💧 #pHMasterAdventures #WaterDetectiveLaughs
