Review: 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.
Review: 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 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.

### ⭐ It works great, until it doesn't
*by M***P on October 14, 2024*

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 :-(
