The Residual Chlorine test strip is for use in ensuring free chlorine levels in drinking water are sufficient to inactivate the bacteria and viruses that cause diarrheal disease, as well as ensuring the water is protected from re-contamination during storage. The strip can also be used to ensure systems have no residual free chlorine after chemical sanitization by testing for very low levels of free chlorine in solution from 0.0 ppm – 5.0 ppm. The residual chlorine test strip is accurate within 5-10% of reading the color scale.
