Start getting accurate water testing results with our simple handheld colorimeter. Our ultra low range free chlorine colorimeter makes it easy to gain more confidence in your measurements. By bridging the gap between free chlorine test kits and advanced instrumentation you no longer have to rely on the human eye to determine colors. Our handheld colorimeter eliminates the trouble of matching to a color chart by providing a direct digital free chlorine result.
The HI762 Checker®HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure free 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 HI762 provides quick, accurate results in four easy steps:
