HI 713 Checker HC Colorimeter - Phosphate Low Range - 0 to 2.5 ppm
The HI713 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure phosphate. Phosphate is a common food additive that enhances flavor and acts as a buffering agent. Important for growth and development of plant roots, phosphate is also present in fertilizers. However, high concentrations of phosphates are detrimental to the environment; for this reason, it is closely monitored in natural and municipal waters.
HI 755 Checker HC Colorimeter - Marine Alkalinity - 0 to 300 ppm
The HI755 Checker®HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure alkalinity. Crucial in marine environments, alkalinity provides both the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, as well as a pH buffer against large changes in acidity.
HI 758 Checker HC Colorimeter - Marine Calcium - 200 to 600 ppm
The HI758 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure calcium. Required for the development of calcium carbonate skeletons of coral reefs, calcium is a crucial component of marine waters. Designed as a more accurate alternative to chemical test kits, the HI758 provides quick, accurate results in four easy steps.
