Indigo® pH 3-6 test strips indicate weak to medium acidity in liquids such as orange juice, milk or coffee. Use them to make sure your home made sushi rice, salsa or kefir acidic enough to prevent spoilage or pathogenic bacterial growth.
These strips are for use in determining a woman's vaginal pH balance & indicate the presence of yeast infections. Normal vaginal pH is in the 3.8-4.5 range, so above or below this can indicate a problem. If you get such readings, consult a physician before self treating.

Needed an easy way to check my materials for canning, especially my tomato sauces. These test strips saved me a lot of trouble since I didn't have to add any special acid to them after I discovered that mine were perfect at pH4.0. THis very simple test saved me a lot of money and i'm very happy with the product
Great news & an excellent example of how to use a test strip to make preparing tomato sauce & salsa easier. This old blog might be of some interest to others: How Does Litmus Paper Work? Not Like pH Strips?.
