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: 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!

### ⭐ Review
*by M***P on 14 October 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 :-(
