• [Auto Calibration]: The SUNZEAL PH meter has an automatic temperature compensation function, which can be adjusted according to the water temperature and water quality, and the pH reading can be obtained almost immediately. Similarly, you can also use "Calibration Buffer Powder" to calibrate the tester with one button.
  • [LCD backlit display]: PH tester bright backlit LCD display, easy to use no matter in the day and night environment, and accurate measurement and clear display results.
  • [Automatic temperature compensation]: The ph meter has built-in (ATC) automatic temperature compensation function, so it no longer needs to take care of the temperature of the test liquid, so it can accurately measure the pH value of the sample at any temperature in the range of 0 ° C-80 ° C (32 ° F-176 ° F).
  • [High accuracy]: PH tester has a sensitive electrode sensor ,simply press "ON", It only takes a few seconds for your result to appear on screen,read accurate pH levels. The included detailed manual will show you how to get the best accurate and stable reading.
  • [Widely used]: Very suitable for home or laboratory use. It is suitable for testing the pH balance of drinking water, swimming pools, aquariums, reverse osmosis systems, hot springs or hydroponics. It is suitable for a wide range of applications.

The LED display makes it easy to read the current PH of the water. We were having PH problems in our aquarium and were looking for a quick way to test other than using the strips. This product solved our need because no strips are needed to test the water. I like that it comes with a plastic storage box and it is lightweight. It is as simple as pushing a button. I like that it has a built in calibration and it automatically compensates for water temperature. My only suggestion would be to add more of the PH buffer powder for future use, but even without, this is a great product. This item is great for anyone who needs to test water for an aquarium. I’m very happy with this purchase.

PH meter works as tested with my filtrated water to be slightly on the alkaline side. Just don't submerge beyond the guided line. See attached picture for reading.

Really easy to use, and I didn't really have any previous knowledge on how to use these devices. Easy to read. It has an automatic temperature compensation is really small. No need to buy consumable test strips and even comes with a case. Happy with this device.

I’m a gardener and I’ve learned that the pH of my soil is important so that my plants and my lawn can take up the nutrients I feed them when I fertilizer or spread compost. I’ve been looking for an easy way to test the soil myself rather than sending it to the university for testing. This pH meter fits the bill. After sifting the samples I collect through a fine sieve, I mix a small amount of soil with about twice as much distilled water. I let that sit for 30 minutes and use the pH meter to get my reading. I’ve found it to be accurate and easy to do.

I use this for measuring the quality of our drinking water, filtered water, and other things around the house. I have found this unit to be fast reading, accurate (when calibrated), and very convenient to use. I wish it included a display of the temperature as well as the pH. This would make it an even more useful tool!

This digital PH water meter is quick, accurate and easy to use. I save money and guess work vs the the traditional paper testers that require me to guess the PH reading of the water in my pool and spa. And no more wasted paper. It has a clip on the back so that I can clip to my pocket and a plastic storage container. The only negative I see, and it can't be avoided if you want accuracy, is having to calibrate the unit. But even calibrating is easy. I highly recommend.

I bought this PH meter to measure the PH level of my pool weekly. I used PH measuring kits before and even they give accurate results, it takes longer to do a measurement with those kits. Thats why I ordered this digital PH meter to make the process faster. For me, I dont need 0.01 acccuracy so this digital PH meter works great for me. It is easy to read and it takes second just to put the tip into the pool and get the measurement done. It is good enough to tell me when to put muratic acid into my pool :) Overall I am very satisfied with the product and I have benn using for almost 2 months now and it seems that the accuracy is not too off yet.

Super easy to use, really accurate reading. Thanks to the ph meter, I now know that my tap and filtered water at home has a better ph than most of the bottled waters.

I use this for the soil and I have one for checking the pool. Easy to calibrate! and seems to be plenty fast read! I like this digital better than strips!

works well, easy to read with the back light. the only thing is the calibration button is close to the on/off button making it easy to accidentally push so you have to be careful.
