Alkaline Water, Tap, and Drinking Water Accurate Measure of pH Level, Test kit wht, up to 125 Tests per Bottle 0.50 Fl Oz by A2O Water - Made in USA

It worked well 😃

My well water is very acidic. The PH is about 5. This test gives good results, much more accurate than a pool test kit, so I know when I need to add more neutralizer to my upflow neutralizer on my well water system.

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

Very happy with this purchase. I'm trying to maintain my pool and there's a lot to know. Did exactly what I needed it to do. Highly recommend!

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.

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

This ph tester does exactly what it sets out to do. With just a couple of drops I am able to quickly gauge how acidic or alkaline my water is.Where I live we have hard (acidic) water so we use a soda ash system to try to neutralize it. It was always guess work trying to figure out how much soda ash to pump into the water. Now with this product I test the water after making the solution so that I can better gauge how much soda ash to use the next time around.Honestly, it's hard to beat the ease of use and price of this product.

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.
