Yeast needs a pH of about 2.5 to 5.5 to ferment. So, if you are having difficulty getting your ferment started and/or your ferment has stuck or is sluggish it is a good idea to test the pH.
As you judge the result by comparing with the colour chart it won't give you a precise reading but these are an inexpensive way to indicate if your must is too acidic or not acidic enough.
Great to have on hand to do a quick test when your ferment is not behaving the way you hoped!
These are not specific to winemaking so can be used to test anything that you need a pH reading for eg soil, water, fish tanks, swimming pools etc
