Real Customer Reviews
Great water meter!
We got this water meter to be used in our saltwater pool and hot tub. This is a very economical and convenient way to test water quality, salt level, and other factors of pool water. Even though this is not the stated intention of this meter, it works well for our applications and we are looking forward to using it weekly through the upcoming summer and year. I like that this unit is small and can be easily put away in a drawer when not used. I would highly recommend it.
Exactly what I needed!
Great little ph tester and even better with ppm and all the other options, too! Accurate against test strips and it was accurate without needing to calibrate it. I use it daily and love it!
So much better than the cheap pH meters
This pH meter is hefty and works VERY well. Instruction sheet explains all about it and it's easy to use. Comes with batteries already installed and with a spare set, cleaning brush and rag. This item had the calibration solutions with it. VERY pleased with it.
