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 the 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. Designed as a more accurate alternative to chemical test kits, the HI713 provides quick, accurate results in a few easy steps.
