Alkaline, Tap, and Drinking Water pH Test Liquid wht(100-125 Tests) 0.50 Fl Oz (Bigger Bottle) by A2O Water - Made in USA

I used this product to test my tap water and several different manufacturers of bottled water. Some of them were stretching the truth with claims of 9.4 pH. I recommend this product.

Works great! It's a multiple use bottle, so I can test several times without having to buy a new kit!

These drops are excellent for neutral to moderately high pH. Not so good for low (acidic) pH, below 7.0.

The media could not be loaded. I tested the tap water at my home and tested water that was ran through a Britta water filter. The pH drops appear to work well as the tap water was more blue and the filtered water turned green.

Works well to test my water and ensure my whole house neutralizer was working. Much better than paper strips (which are near useless for this purpose). Not quite as accurate as the Hach set (as requires comparison to the printed label, thus subject to some variation depending on lighting etc) but a fraction of the price. Recommended.

I like to test the ph level of my drinking water.These drops work great

I've known people to use the particular drops for soil testing, but I personally use them to test the drinking water whenever staying somewhere I don't go to very often, or when showing friends the wide array of differences in PH levels for all brands of bottled water. Its always a big surprise to them and the look on their faces is priceless!

Product itself seemed to work fine for a Science project.Delivery not so much. We ordered in advance and it was delayed/lost/never arrived.Arrived later than expected.Order way in advance if needing just in case.
