GOOD Based on 216 reviews Posted on SunnyflacatMarch 2, 2026Verified So glad we got this! We needed this to check on sodium level of our whole house filtration system as we felt something was off. And it was! We were drinking water that was 400ppm!! So glad we got this so we can keep a check on it. Having an RO system installed under the sink. Jacksonville Florida has awful water. This meter works great!Posted on JohnJanuary 20, 2026Verified Value for your money Calibration accuracy the quality was goodPosted on MattJanuary 4, 2026Verified Only decent for TDS Ph, salinity, and temperature are unreliable and inaccurate. Ph is all over the place even after calibration. Same with salinity. Temperature takes an absurdly long time to stabilize and even after that it isn't correct. TDS seems to be the only reading that will deliver repeatable results.Posted on amazon fanSeptember 18, 2024Verified Reliable for salt and PH for inground pool The readings are consistent. I have used it to test salt and PH since July. It is reliable and is close to the pool store results. Pool store results vary as we know. This is a good tester. I can swag how much muriatic acid to add to reduce PH. I test after a few hours and it’s down to range. I test at the pool store and the PH is in range. I like using this tester. I’ll buy the calibration packets to calibrate next season. I recommend this tester. The company website was very helpful with tutorial showing you how to use it and calibrate it. We’ve had our pool for four years. This is much better than the cheaper tester I bought last year. That cheaper tester was not reliable. This is worth the moneyPosted on JDHJune 30, 2024Verified Great meter for salt water swimming pools. Purchased this meter as I was tired of wondering if the salt ppm levels were correct on my chlorine generator setting. Also it is excellent for Ph readings. This meter is super accurate, easy to use and well made. Be sure to watch the YouTube video from the manufacturer to get the most from the meter.Posted on rosemarie roussellDecember 14, 2023Verified Best one Works greatPosted on Dankmaster1996November 20, 2022Verified Better and more accurate than Blue-Lab I needed an emergency Ph pen when my RYKO probe broke for plant watering late at night. I decided on Aero-gro as my choice, when it came, the calibration wasn’t hard. Nice case too. I also decided to try Blue Lab ph pen, Which was double the cost with calibration solution and Ph 4.0 and 7.0. Blue lab has no tenth decimal. I felt it was inferior and too simple to Aero-Gro. The pen is very accurate. The readings get slower within range. I only care about Ph range but sometimes it’s point on, and will stop. Not even RYKO was that steady. The ppm seem accurate too, testing against the Blue Lab truncheon stick. This is a good and reliable professional quality Ph pen. As good as a Hannah or OaktonPosted on PeiperOctober 24, 2022Verified Love this meter!! So easy to use!! I love that this meter is waterproof and that it can also measure salinity. In our house we use a pH meter and TDS meter mainly to check the aquarium pH and to test our Reverse Osmosis filter efficiency. Because this meter is waterproof, I can now safely let the kids use it without worrying that they’ll drop it in the water. Great feature!We have very hard water where we live, so the TDS meter helps us monitor how our water softener and R.O. system are performing.The saline % feature is also really useful for us. We like to add just a little bit of salt to our freshwater aquarium, and this meter lets us measure exactly how much salt is in the water before we pour it into the aquarium.The how-to videos on the website are really helpful and easy to follow. There’s a scannable QR code in the instructions that will take you right to the videos. There’s even a video that shows how to calibrate the meter. It’s much easier to calibrate than I thought it would be.I’m very happy with the meter as well as the customer service!Posted on John GauweilerSeptember 29, 2022Verified Excellent Product! We purchased this meter as a replacement for an old, dedicated TDS meter that finally died. We primarily use a TDS meter to test our filtered drinking water, so we know when it is time to change the filter cartridges in our R.O. water filtration system. When the TDS is over about 40 or 50 we know it’s time to change the cartridges.Since this new meter is a 5-in-1, we now have a meter that can also test the pH of our aquarium - and we don’t even need to use the pH test strips anymore! The meter also has a nice, bright display and is easy to switch between the different modes. The “Hold” function is also really helpful when measuring pH.There are very nice printed instructions, and there’s even a QR code in the instructions that takes you right to the online video tutorials for the meter. Love that! The videos and other information on the Aero-Gro website are easy to follow and really helpful. There’s even a video on how to calibrate the meter using the included buffering powders.The meter feels well-built and is quite sturdy. It’s also waterproof - which is nice in case it gets dipped too far into the water. Very nice meter!!Showing our latest reviews
