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

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!

Been using the Ph meter for a couple years now. It continues to provide consistent and accurate Ph readings of my pool water. No chemicals or colored drops needed. Very slick!

Doesn't hold calibration for very long but it's a good deal for the price if you don't need the pH to be accurate to 2 decimal places. I'd trust it to the one's place. Works fast, holds up well, just don't drop it in solution or you'll have to take it apart, clean it well and let it dry for a couple days before recalibrating.

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.

Would definitely recommend it since is a great value 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.

Worked really well and is easy to use! super small to so easy to store! 1 would say it's a good value for your money!

Value and work great for each grow then disgrace re calibration does not work.
