DOY PH Tester Meter Digital for Water, Hydroponics, Aquarium, Pool & Food PH Test for Hydroponics(0.01 / High Accuracy /- 0.05 and 0.00-14.00 Measurement Range)-Yellow

Batteries fell out of the first one when I first got it it was easier just an order another one on amazon.com then it was to run to the store get batteries LOL... but anywho, they work great I just wish you didn't have to calibrate them but that's no biggie it's easy to do and you only have to do it every once in awhile but I suggest buying the pH calibration buffer powder with it cuz you'll need it and I don't have a clue how to work that other blue mechanism LOL busy busy busy not enough daylight in the day but yes I highly recommend pH in your veggies if you're going to if you want a good outcome

once i got over the initial fear of the doing the calibration, which actually was super easy i checked it on two tanks that were recently tested so i knew the PH level, was super accurate.

Mine was broken upon arrival.

Works great was on time and packaged great and once again perfect.

Exellent product with an excellent price. Easy/simple to use on liquids

I am so upset the darn thing stopped working. I was happy with the Item so I ordered a second one - BAD LUCK at the same time, after less than a month of use the unit stopped working. It does not read correctly. I went to review it on the original order I made and it wont allow me to review or return. Very SUSPICIOUS! It is locked at 5 star review! I GOT A BUM DEAL. IF THE SELLERS WANT CONTACT ME & TO DO THE RIGHT THING AND REPLACE THE ITEM (IN BLUE), I will delete this Review and chalk it up to one defective anomaly - otherwise I will have no choice other than to make multiple comments warning people because now I am scared this second one is going to break on me and the lock on the 5 star review is super shady!
