Great Little pH Meter!
For anyone with hobbies that depend on the pH of something, this little digital pH pen is a fantastic tool to have in your toolbox. It takes all the guesswork out of the process. I use it to keep the water in our fish tank just right, and it’s super easy to use. One thing I really like is that it also measures the temperature at the same time as the pH, ensuring my heater/thermometer is working as expected. It comes with calibration powders so that you know your readings are really accurate. This meter is exactly what I was looking for: simple, effective, and I highly recommend.

The Perfect Tool for Monitoring Water Quality in Las Vegas!
I recently decided to take control of the water quality in my Las Vegas home by installing a water softener system. Living in an area where water hardness can be a significant concern, it was crucial for me to find an accurate and reliable way to monitor the pH levels of my water, ensuring it remained within a healthy range for both drinking and household use. After much research, I stumbled upon this water pH tester, and it has been an absolute game-changer for me. The accuracy of this pH tester is impeccable, giving me peace of mind that I’m maintaining the perfect balance in my water. The ease of use is another standout feature; it’s as simple as dipping the tester in the water and reading the result. No complicated procedures or calibration issues that I’ve encountered with other testers in the past. Its durability and build quality are impressive. Living in a desert climate like Las Vegas, where the conditions can be harsh, it’s essential to have a robust tool that can withstand a bit of wear and tear. This tester has lived up to that need splendidly. One of the aspects I appreciate most is the immediate feedback it provides. This allows me to make any necessary adjustments to my water softener system in real time, ensuring that my water quality is always at its best. Whether it’s for the health of my family or the longevity of my household appliances, this pH tester has provided an invaluable service. I highly recommend this water pH tester to anyone looking to take control of their water quality, especially for those living in areas prone to hard water. It’s an essential tool for anyone with a water softener system, or simply for anyone who cares about the quality of the water in their home. Five stars all the way!

It works great, until it doesn't
This review is going to be a bit daunting. Out the gate when you first receive these meters they tend to get the job done. Reads the pH well, gives accurate PPMs, etc. All is well up until the first battery swap That's when things get bad. You can no longer calibrate the meter with the pH solution provided, which makes the product utterly useless. I bought another one of these and within first use out the box, the diode completely shattered on me when simply trying to clean it off with a wet paper towel I've purchased about 4-5 of these and I'm pretty much convinced at this point that they're not reliable after some wear and tear. I have an older Vivosun meter that's been sitting dormant in its packaging for well up to a year now, and is still more calibrated than this meter is after a week of solid usage. It's time to move on. There are much better, longer lasting options than this meter :-(

Great tool for saving me money!
Works as advertised, I use to monitor my water quality after it goes through my RO system to verify when I actually need to change the filters. Live in AZ, water straight from the tap is approx 553 ppm, it's zero after the RO system and I check it monthly to see when it starts to rise so I really know how long my filters are lasting. It's extended my filter change intervals by 4 months so it's also saving me $$$!!

pH values fluctuate for a long time
I bought this digital pH meter to replace my old bromothymol blue drops for testing the pH in my aquarium. But, the pH value of this tester jumps around wildly, such as from 6.55 to 7.11 or more. The value VERY GRADUALLY stabilizes but takes about 3 minutes or more, which is a long time to wait. The bromothymol blue testing would actually have be quicker. While waiting, the display backlight goes out forcing me to press the Hold button twice to get it back on. The digital tester pH value changes about 4 times a second, which makes it difficult to read since it varies all the time and never settles on a single value. (I see why they added a "Hold" button). After "stabilizing", the value still jumps around, such as from 6.87 to 6.94. Also, the temperature seems off by 2 degrees. This digital meter shows temperature of 75.9 F, whereas my glass thermometer shows 78. And my crude adhesive strip thermometer shows 78-80 (closer to 78). Luckily I don't need this device for temperature, only pH. On a positive note, I have seen the tester displays pH values down to 4. Whereas the bromothymol blue testing only indicates pH values from 6.2 to 7.4. The digital tester also has a nice display with a green backlight. I have been using this digital pH tester for about a year. Waiting for the pH value to stabilize is very annoying, but I appreciate the wide range of pH values it can measure. Following are some suggestions for the company and their engineers: 1) Please use a running average to smooth out the pH value the device displays. There's no use in seeing a value immediately change from 6.55 to 7.11. I would prefer that it displays a slowly changing pH value, blink the value while it is changing and has not stabilized, and then stop the blinking when the value stabilizes to about 0.1 pH. 2) I do not see any use in displaying pH values down to 0.01 pH. This tester never stabilizes to an accuracy of 0.01 so what's the point of displaying it. I would be happy to see a pH accuracy of 0.1 as long as it stabilizes quickly. 3) Please make the green backlight stay on continuously. 4) Do not change the pH values 4 times a second, at that rate it is difficult to read any one value. One or two changes per second would be sufficient. 5) Improve the accuracy of the temperature. By displaying temperature down to 0.1 F you are implying that is also the accuracy. But in my experience the accuracy isn't even 1 degree.
