pH Test Strips 0-14: 200 Strips Universal Litmus Paper pH Test Strips for Liquid Testing & Water & Food and Soap Making, Get Highly Accurate Results in Seconds

pH test strips from BACNUNN are so easy to use. The handy color chart on the back of the box allows you to test the pH of your water is seconds. I used it for the water in my cold plunge pool. Excellent product and a great value for price.

good, like the long stem. with only 2 testing patches

I usually do not leave reviews, but this product is outstanding! I’ve tried two other test before buying this one and this one is spot on! I use it for my canning goods. Highly recommend! Test results are within seconds. A+ product!

Initial tests showed bleach at pH 13, white vinegar at 2, and two different spring waters at around 7-8. My purpose of buying these strips is to test water for coffee. The strips seem to work well. I'm a little suspicious of the near neutral spring water tests, but this will take further testing to determine the efficacy of the strips. If the neutral area tests are correct, then this product deserves 5 stars. Will update this review in the future.

water testing

I love this product! It is very easy to use and very relevant. I checked filtered water, wTer bottle and from the sink, they came up different. There is so many tests in the package so that it can be useful very often if you want to check PH levels. I am grateful that I found them.

Good product.

These only measure acid, not base, so they are totally non-functional to advertised purpose. Defective product, and not just one strip but all of them, in sealed bottle. I tested on acid (vinegar solution) and base (salt water) after trying repeatedly for intended use and only getting a "6" (neutral) reading repeatedly. The strips did react with acid, but could not measure a base higher than neutral. 4oz of water and a teaspoon of salt measured a 6. As did every other non-acid liquid I tested. Scam. If the strips didn't measure acid OR base (meaning failed on both) you could say there are just some one offs in orders. The acid reaction tends to confirm this is a knowingly fraudulent product.
