1. Take one strip from the pack and dip it into the solution you would like to measure. The color of your strip will change immediately.

2. Quickly match this color against the color chart on the inside of your pack to obtain the pH. Do not wait or let the strip dry!

3. The number next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutral.

Please note that solutions with a pH of ~5.5 will result in a yellow colored test strip that resembles the original color of the dry strip.

Store in a cool, dry place away from sunlight.

    Work Great- Cost Effective!
    Simple & cheap way to test the ph of our stripper neutralizer in our powdercoat shop. Sometimes we test several times a day as we adjust the pH. These strips show instantly and are far more cost effective than plastic strips.

    Cheap and work great. Couldn’t find in any stores in town. Did find some pool strips but they only showed a limited range. Soil ones were expensive and required powder (which they only included 10 uses) and they only went to 4.5. I needed it to be between 3-4. Awesome that it’s full scale from acidic to basic. It can be hard for an accurate reading but it gets you in the general area that I am going for. Plenty of strips too!

    It’s litmus paper. Not much to say except it works and it’s a whole lot cheaper and less of a hassle than calibrating meters all the time

    Wow! I was about to write a scathing review because I have tried it on every bodily fluid I have over the course of a week and there was no change in the color of the strip. However, something stopped me and I read the seller’s statement about the color not changing when the liquid tested has a neutral pH. I decided to try it on other liquids I know are acidic. The strips worked perfectly! I am thrilled!

    I love that these are paper and not plastic, so they can be flushed or disposed of in the garbage without adding more toxins to our world.

    I do wish better instructions were included with the strips that explained that there would be no color change with neutral pH. It would save frustration on the part of the consumer and reduce negative ratings and reviews.

    These marvelous little test strips not only measure a person’s pH level quickly and easily, but will also measure that of my garden soil!

    We do have our priorities, do we not? My garden is very, very special and keeping a close eye upon the soil pH level is crucial for best productivity. My garden soil or a planted container’s pH is checked almost as often as my doctor likes my own tested! So inexpensive and quick, with the color chart right there in your hand.

    Litmus pH Test Strips package is one of those little things that make life easier and an important task faster. I will be keeping them on hand from now on.

    This is the cheapest litmus paper pad on Amazon. I bought it to test pH of my wines, and it works perfectly for that purpose. It’s PAPER, and for rough checking, not .01 accuracy.

    Btw…. to test SOAP for alkalinity, it doesn’t make an iota of difference how old cured soap is, unless you made it lye-heavy, it’s going to test between 10-11 pH. If you superfatted the heck out of it, it may be as low as 9.5 pH. You aren’t going to see variations between batches unless you REALLY screwed up with the lye…. at which point, you are going to see white lye spots/dots/streaks rising to the surface of the soap in the form of powder. Unsaponified lye has no oils to bond with, so it stays unbonded… and as it dries, becomes lye again. This is hard to miss. It’s unreasonable to downgrade litmus paper because you don’t understand soap saponification.

    On the other hand, if the litmus paper is really old, it’s not changing colors no matter what you dip it in. I’d test bleach in the laundry room and then vinegar in the kitchen to see if that’s the case. It’s not hard to figure out if the paper is defective.

    Works as it should. Great value for the quantity compared to other brands on Amazon.
