KH tester: 5ml of water sample. Count the number of drops of solution needed to change the solution from yellow to blue. (Hope I do not remember the colour wrongly.)

pH tester: 5ml of water sample. Drop 4 drops of solution to water sample. Compare the colour to the colour chart on the instructions. (Now that's gonna be a problem if you have lost the instrutions.)

Look at the label on the reagent bottle, it usually shows there in graphical form. For KH, it's 5ml water. Never used the pH one before.
