Great household pH meter
Christine E. Nattrass✓ Verified Purchase•July 28, 2023
I'm a homebrewer and I got one of these for measuring the pH of my grape must. I'm also a cook and a physicist and I like being able to measure the pH of lots of things. This is a nice balance between price and accuracy. This is probably as accurate as you would need for any household application. You need to have a buffer solution to store it in and you should have two solutions for calibrating. It's not trivial to use properly (you should read the manual) but it's not difficult either.
Accurate Measurements. Reliable Instrument

I have been using the Hanna pH/Temperature tester for two months now. It gives relatively accurate readings, and is easy to use, and calibrate (using the calibration solutions...sold separately). I keep mine submerged in a balanced salt solution. It is critical to keep the electrode hydrated at all times. If it should dry out, the life of the electrode will lose its accuracy, and may have to be replaced. I use mine to gauge the acidity of cheeses that I am making from milk products. The reason I only gave it a 4/5 is because you must recalibrate it after4 each usage. You must also purchase the standardizing solutions separately....an expensive proposition in the long run. But, I would purchase this model again.
Hanna is the best.

Taking my local extension Master Gardner program we used these to do soil tests. Since then I have started my own lawn care company and I tried cheaper ones with very inconsistent results. The Hanna works very well, plus they have headquarters only a few miles from me!

When your whole aquarium relies on these two fundamental elements you don't really need anything else. Calibration is easy. You get a reading in 15 seconds. Easy to keep an eye on your tank.
Would be better if the bottom was flat

Accurate, efficient, compact, and waterproof. Not much else to say about it. My only complaint is that, since the directions state that the sensor should be stored in a few drops of storage solution, you need to keep the device upright when storing it. The rounded bottom makes this difficult. Would be better if the bottom was flat.
