pH Test Strips for Urine & Saliva: 200 Strips pH Paper for Body pH Testing 4.5 to 9.0 - Acid Alkaline Litmus Paper pH Test Strip for Humans

I had read some negative reviews (1 stars) on this product and was a little concerned. However, I read the instructions and using some test equipment I verified they do work. I'm not suggesting they're 100% accurate but they are easy to use, seem a great deal for the price and from testing they seem to provide results very close to other test equipment I compared them to. I tried them on RO water, tap water etc. If there's one thing I think that might cause confusion for some is the color strip chart. These strips can give a very subtle color variance based on the water type tested but the issue here is simple... you're not testing for marginal variances... you're testing for water that is clearly acidic or alkaline which for me, makes these perfect and simple to use.

I bought these pH test strips mainly to check the alkaline water I use for brewing coffee. The results were quick and surprisingly accurate, especially at the high end of the pH scale.What I appreciated most was the ease of use. The included color chart is simple to follow, and results show up in seconds. The strips are stored in a resealable bottle, which helps keep them fresh and ready for multiple uses.Just make sure to read the strip quickly before it dries, since the color can fade over time. Overall, a solid and accurate tool for the price.

For the price these seem very accurate, sanitary, and good quality.

The media could not be loaded. These ph strips work instantly. We bought them because we make soap at home and need to make sure it is done by checking the ph level since we cant do the clear water test, we have hard water where we live. I dipped them in the soap water and they came out neutral! Just to make sure these work for other ph levels, we sprayed vinegar mixed with water, and the ph level changed to very acidic. So id say these are very accurate.These are extremely easy to use. Just need to dip it in the liquid for a second and you get the results. For the vinegar test i didnt dip it in but it still gave me accurate results and the colors matched easily to the chart provided.

These worked well for me. The two colors per pH level took the guess work out of interpretation. I don't think it would work for most people who are colorblind, though.

These ph strips are easy to use and gives instant results. Compare clear result using the included color chart. They’re perfect for checking pH in water and food and the resealable bottle keeps them fresh for longer.

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.

Simple test strips that do the job easily. Also, they seem to store well. Not sure if they have a shelf life where the accuracy goes down.
