These are tools designed to measure the concentration of chlorine in a solution, typically water. These devices usually consist of a small strip of material impregnated with chemicals that react with chlorine. The resulting color change on the strip is then compared to a reference chart to determine the chlorine level. For example, they are commonly used in swimming pools, spas, and food service environments to ensure proper disinfection.
Maintaining appropriate chlorine levels is crucial for effective sanitation and the prevention of waterborne illnesses. Inadequate chlorine concentrations may lead to the proliferation of harmful bacteria and viruses, while excessive levels can cause irritation and damage to equipment. Regular usage provides a simple and cost-effective method to verify that chlorine levels are within the recommended range, thereby contributing to public health and safety. They have become increasingly prevalent over the years due to their ease of use and affordability.
