2 Pack pH Test Strips, 160 Strips pH.1-14 Universal pH Test Paper Litmus Test Paper Soap Making Testing Strips for Water Wine Saliva Urine Soil Testing Pet Food and Diet pH Monitoring (Sealed Pack)

I use these with my cat that is prone to urinary tract infections. Really helps me stay on top of her health.

Convenient little folder of Litmus strips for pH testing, color chart included.

They actually work ! And it’s great they in small pkg

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.

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.

Waste of money… Didn’t work maybe I got a pack of construction paper but never changed color besides a damp look. I guess it depends on if you get a good batch or not because I don’t know.

These strips are very straightforward. I love that they come in two separate packs so I can keep one in the kitchen and one in the garage. The paper is sturdy enough that it doesn't fall apart when wet, and the 1–14 range covers everything I need. Great for quick checks without needing a digital meter.

Easy to use. From left to right. I expected more color difference between Saliva & Chlorinated Tap water? Salt water, Dill pickle juice & Ice tea all look the same pH. Not sure if I did testing correctly. Additionally, center photo is Distilled water, far right photo is tap water that sat in open containers for 6 hours.

Works just fine

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.

Great for testing soap pH

Here's my experience. I used them on straight water and it tested about where I thought it would be. I used them on lemon juice and it tested where it should be. I added lemon juice to water and it seemed to take about six times the amount as per a chemically tested recipe to increase the acidity than it should have. It seemed like at the extremes these are measuring just fine but the subtleties between aren't working. Are there variances in the acidity of lemon juice probably but I also tested the lemon juice and it was at the average where lemon juice is supposed to be... As per the strips. Unfortunately my control measurement is from the very strips that I'm testing. I nearly killed a lot of plants with high acidic water because I saw no change in the color until I added quite a bit of lemon juice to the water. I tried the water on a couple plants at the 6ph that it should be according to the strips and they nearly died. They did not enjoy that at all. So like title says I'm really not sure. I think these detect acidity and pH at the extremes but aren't working to the subtleties they're supposed to. I did everything with single drops as per the instructions and again unless there is an extreme change in the acidity I didn't see any change in the pH test paper.

These pH strips were disappointing and didn’t work as advertised. The readings were inconsistent and hard to interpret, especially when testing my hydroponic garden solution. Accurate pH levels are critical for plant health, and unfortunately, these strips didn’t provide reliable results. I wouldn’t recommend them for hydroponic use.
