What are chlorine test strips used for?

Chlorine test strips are used to quickly and easily measure the concentration of free chlorine in water. Free chlorine is a type of disinfectant that is commonly used in swimming pools, spas, and drinking water systems. It kills bacteria and other microorganisms that can cause disease.

Chlorine test strips are typically made of paper that has been impregnated with a chemical that reacts with chlorine. When the strip is dipped into water, the chemical on the strip reacts with the chlorine and changes color. The color of the strip can then be compared to a color chart to determine the concentration of chlorine in the water.

Chlorine test strips are a convenient way to monitor the levels of chlorine in your swimming pool or spa. They are also a good way to ensure that your drinking water is safe to drink.
