NOTE:
This paper does not apply to buffer solutions and very weak acid-base solution concentration lower than 0.01%.
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.
Instructions:
1. Take one strip 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 package to obtain the pH in 15 seconds. 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.

Not reliable for plant care
Not accurate enough for PH testsling water for my plants, so I bought a quality PH meter and ditched these.

They work as advertised
I used a base to bring an acid up to the level I wanted it to be. These worked perfectly for my needs. The colors are off in the picture because the strips dried before I took the picture. I also cut them in half before use, so they look shorter than what they are right out of the package.

ACCURATE
I LIKE THE LEVEL COLORS INDICATING THE ALKILINE LEVEL OF THE TESTED ITEM
Jared Ray –
Awesome
Works very well. My tap water was registering around 7-7.5. I added about 1 teaspoon of hydrated lime to that same liter of water and raised the PH well into the 14 range and was totally purple.There is a comment saying these donât change colors – itâs likely cause whatever was measured is likely neutral still. I have observed both alkaline and acidic changes on these papers. Learn how to use them, itâs not hard.

USELESS!! STRIP DOES NOT CHANGE COLOR.
Totally useless. Strips do not change color, paper just gets darker yellow/orange because it is wet. Tests the same for orange juice (acid) and water with baking soda. Total waste of money.
