Achieve accurate water testing results with our simple handheld colorimeter.
Trust your readings now, our low range phosphate colorimeter brings you more precise technology than your average chemical test kit. By determining your results digitally, our handheld colorimeter eliminates the effort of matching to a color chart.
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. Designed as a more accurate alternative to chemical test kits, the HI713 provides quick, accurate results in a few easy steps.
