PH RANGE INDICATOR PAPER

Can be used to measure the pH of water, soap, lemon juice, vinegar, milk, liquid detergent, moisturized soil, saliva, urine, sweat

• The 10 Books per pack (Each book contains 20 Papers).
• High accuracy pH test paper, pH range from 1-14.
• The pH 2-10.5 color chart with each book The test strip color changes must be matched with the pH scale color chart within about 15 seconds.

Suggested Use: To perform the test, place a drop of liquid sample on a small strip of paper or dip a piece of litmus paper in a small specimen of the sample. Ideally, don`t dip litmus paper in an entire container of a chemical—the dye could contaminate a potentially valuable sample.

Limitation: The litmus test is quick and simple, but it`s not an accurate indicator of pH; it does not yield a numerical pH value. Instead, it roughly indicates whether a sample is an acid or a base.
