The Hanna Phosphate Low-Range Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Phosphate Low-Range Checker® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.

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 four easy steps:
Features at-a-glance:
Easier to use and more accurate than chemical test kits
Dedicated to a single parameter
Small size, big convenience
Ideal for: Water Quality, Aquaculture, Education, Agriculture
