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

I would buy these again as they work well~!

Accurate and will last a while for measuring pH of solutions. The container seals easily to prevent soaking all of them in a solution.

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!

Good product.

The description is confusing saying that the test strips are for all liquids but this product doesn't work for testing urine and saliva, it shows neutral pH throughout the day. Other test strips I'm using do show acidic, neutral or alkaline pH environment. I also tested these strips with vinegar, tap water and bottled water. The results have to be read almost right away because when the liquid dries out on the strips, the color changes and fades. So, if you don't mind that, the product is fine.

I have tested these so far on tap water, ZeroWater and concentrated vinegar. From what info I can find online as to the ph levels of what these 3 things should be, these strips appear to be accurate. Much easier to accurately read than single color litmus paper and I can tell to within 0.5 difference of ph, which is good as I'm using these to test the ph of the water I'm using to water my carnivorous plants, which require a ph ideally between 4.5 and 5.5. I THINK a lot of the complaints that they "don't work" is because people are ordering the wrong type for their intended purpose. There are 2 types here: one with a range of 0-14 for all liquids, and another that's a more narrow range (I forget the exact numbers) for saliva and urine. MAKE SURE YOU ORDER THE CORRECT ONE FOR YOUR INTENDED PURPOSE!

I'm not sure these work. Unfiltered tap water, filtered tap water, and bottled water tested exactly the same and barely changed the color of the strip, if at all. I even tried another beverage, just to see if the color would change and...nothing.

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.
