Ive been using ph meters for 11 years.This one by far is better than Ive ever used.If you need accurate meter this is the one for you.
We were very happy with this Apera ph20 Ph tester. We grow ceritified organic microgreens for the local csa and chefs and need a reliable and easy to use tester for our water. Our deep well water was tested by a local lab and found to be the 'perfect' water with no contaminates or heavy metals. The Ph however is perfect for us humans at 8.8 - 9.2 but not so for delicate microgreens. So we had to buy a certified organic Ph-down to bring it down to 6.5 - 7.5 depending on the type of microgreen. The Apera Ph20 is one of our most important instruments now and we have found it to be highly reliable and easy to use.
Thank you Apera!!
Great product for a great price. Upon using the PH meter I had to calibrate with the different buffer solutions. It was a snap to do the initial calibration. As a home brewer I have used this several times now and have not had any issues, it works like a charm and stays in calibration. I do double check the readings with the buffer solutions before use to verify. I highly recommend this product!
Great budget PH meter. I use it for brewing beer at home and it is very reliable and accurate.
This pH meter has blown me away. Not only was it extremely easy to calibrate, but it reads incredibly accurately as well! I had many of those cheap pH meters, but one by one they would break, or stop being accurate. So I finally decided to buy a more expensive one, and boy am I so happy I did!
The pH meter itself calibrates easily and responds quickly to the solution being tested. The temperature probe is quite slow to respond (which may also effect the final reading on the pH meter). However the temp probe does read within 0.2 of my reference temp probe, so accuracy appears to be quite good.
First I needed a PH meter to measure PH in my pool and spa. I tried test strips and a bunch of the $20 or so meters which are not good. As soon as you unpack this meter you notice something special. It comes in a very expensive shock resistant box and even has premmixed liquid calibration solutions, two different PH levels, and excellent instructions. I have run multiple tests on my pool and spa and it is so easy that I am moving to daily testing. It even comes with a little cap with a fill line that can be used for testing instead of having to use a cup or having to dip the stick in the pool. This meter feels like it should be 5X the price of the cheap ones on the market. I also bought a pool testing kit with the food coloring and clear tubes which I plan to use weekly and to cross validate the results of this meter. There are many good youtube videos about the calibration process. It is a little unclear, at least to me, how to conduct calibration until you either see the youtube video(s) or follow the less wordy version of the instruction about calibration the right. It is simple once you understand it. Terrific PH meter and very easy to use!
I have used a lot of different ph testers over the years with mixed results and I have been using this one for two grows and so far it is working really well. The packaging that this device comes in is top rate the case comes with 4/7 calibration fluid and is quite sturdy.
Moved over to this instrument from Hanna checkers that died after 2 weeks to a month.
So far this hasn't died or needed storage solution just cleaning with pure water. (distilled)
It also sports a temperature read out and a little more then the simple Hanna tools.

I recommend this over Hanna and I have tried both of Hannah's around this and they are the
same price and I was disappointed. If you need an affordable PH checker this is your tool.
Comment from MP: Hey bud, this is from the product description: (Do NOT store the probe in distilled water or deionized water because they will cause damage to the glass membrane of the pH probe. Only use distilled water for cleaning the pH probe.) Don't want you to damage that purty pen.
Works well for my purposes. However if you leave this device in the solution for too long it's reading seems to keep dropping. so believe the reading when the smile face indicator first appears. I know because I tested it with other PH testers. Remember to shake to bubbles off the probes each time you stick it in the solution.
