This a great little tool. I have a hottub and the test strips kept going bad due to the moisture in the air. This is the perfect tester for testing pH in the hot tub and will not go bad.

This water tester takes the guess work out of measuring ph for my spa. No more comparing colors on a strip to a chart. Comes with spare batteries as well. I recommend this water tester

I think this item would have worked great I just didn't understand how to use it, nor did I have the patience. I think it would have been accurate and worth the money. The design was great, and it seems easy to use I was just looking more for the paper strips at the time. It also seemed pretty durable and was made to be accurate.

Great product! Like how it comes with all you need to calibrate the PH probe (also has extra calibration powders). Accuracy is spot on when compared to my test strips!

When you get something that fails at an alarming rate of speed like this, it’s worth writing a review for. The Ph setting would randomly disappear from the available menu choices. It wasn’t readable at all. The salinity reading was far off & inaccurate. The screen would blank out & be of no use. The bottom line, quickly run away from this one and stick to test strips like me.

Super fast shipping, this productWorks fantastic, no more trips to the pool store, highly recommend!

Great Product...very accurate readings!

Tester works great. Easy to use.
