The HI761 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure total chlorine. Chlorine is a popular disinfectant used in municipal water, fruits, and vegetables, as well as equipment in the food and beverage industry. Though beneficial in destroying pathogens, levels greater than 4 parts per million (ppm) is harmful to humans and therefore, must be monitored. Designed as a more accurate alternative to chemical test kits, the HI761 provides quick, accurate results in a few easy steps.
