7 Pack pH Test Strips, 560 Strips pH 1-14 Universal Litmus Test Paper for Soap Making Water Wine Saliva Urine Soil Pet Food Testing (Storage Case)

These seem to work when you need a pH measurement in a pinch. I wouldn't use these for accuracy, but are easy to use and the colors change according to pH chart.

I bought these to test the Ph of skincare products, because my skin can get alllll angry if I'm not careful. These work almost instantly, it's a nice big test strip so easy to read, soyou're not squinting at the color chart, and they're a really good deal. I will probably not use even half of these before they expire, but I will buy them again when that happens.

This item is of the most help when making Homemade Vinegar. I was sure if I had completed the fermenting progress until I tested it with these strips. They are also handy for testing the PH Levels in my fish ponds and aquariums making it versatile in uses. The Color change gives you a fast answer to what the levels are. Colors also make it easy to read.

Ph value for most part is accurate but functionality is a lil iffy the rooms light or sunlight kinda changes it to where it’s hard to tell it says keep outta light which I get but kinda hard to tell the ph color then.

Bought these to test the ph of my fish tanks before adding triop eggs and they worked perfectly and were very easy to read! Triops are extremely sensitive to ph and they hatched within 24 hours so id say these are very accurate strips.

They do NOT WORK. I bought these to test my semi hydro nutrient solution once nutrients (silica, cal/mag, foliage focus) are mixed with my Colorado tap water and it doesn’t matter if I put straight tap, individual nutrients, or the whole solution- the paper doesn’t change AT ALL. Idk if they’re old or what, but they suck.

Helpful to have... I take bicarb frequently to help low sodium and urine pH tells me if I'm getting too alkaline or not, very important to know

Typical pH paper. Don't use these to read the pH of a pool as it will not work. The pool chlorine can chemically react with the pH indicator dyes on the paper and will not change color.

Really nice product. Strips tear out easily and very easy to read. I had three different water sources I wanted to check and you can see by the pic, the differences (which I completely expected) showed very clearly (would be easier to see if I put it on a white background for u to see) Only suggestion is to have the comparative color guide on the outside of the cover and not inside. I don't want to contaminate the unused strips accidently even though there is a minor chance of it happening. The white page directly beneath the strips (which covers the unused strips) is also nice, but would be better on the side to more easily compare with the color chart, but overall a great product.

The strips are pre-cut into stacks within the booklets that make them easy to use. I calibrated them with some substances I knew the pH of (baking soda water, distilled water, and lemon juice and found them accurate.

This pH strip test is highly effective and comes highly recommended. It is straightforward to interpret the results, which are available within a few seconds.

It did exactly what it say it would do

It doesn't work with creams or thick shampoos...so it was kind of useless for me. You can test kefir if you want to (just tried for fun) and all clear stuff - like Dr. Bonners and it works. However, even if I tried to mix thicker creams nto distilled water - it just didn't work. I'm going to keep trying but I think the way forward if I want to know what ingredients should be there and what should not.
