The Diagnostic ph test strips by PH Ion-Balance measure the body pH of urine and saliva in a wide range of accuracy from 4.5 to 9 pH. The results can be read in 15 seconds and are accurate.
Each strip contains a picture of what the optimal saliva pH result would be. This helps you quickly compare your results with the desired results without having to refer to another chart necessarily.
The box contains a useful color chart which accurately shows the pH of urine [top row] and saliva [bottom row]. The chart will also give you the ranges to help you analyze or your health practitioner diagnose your results [very acidic, acidic, optimal, too alkaline].
