Indigo® pH 3-6 test strips indicate weak to medium acidity in liquids such as orange juice, milk or coffee; only $5.95 /50 strips.


These strips can also be used to test for 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?.

So prompt, so accurate. I only order from them. They are the best!
