It's great for household drinking water, swimming pools, hot tub, spas, aquariums, hydroponics, kombucha and beer homemade and more.

Kindly Note
These paper strips will only provide you with a rough pH value of the solution to be tested, and if you require exact and accurate pH readings, then you might need to get a pH meter.
In addition, since in most cases the pH values of solution are not exact integers, the resulting colors of the stripes would not necessarily match any column of the comparison color chart exactly, and you could choose the nearest color column as the final result.

Instructions
