The Hanna Phosphorus High-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 Phosphorus High-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.

• Compact, Portable Design
• Built-in Timer
• One-Button Operation

The HI706 Checker®HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure phosphorus. Common in natural systems, such as lakes, oceans, and soil, phosphorus is an essential element in plant growth. However, when present in large concentrations, phosphorus can cause excessive microorganism and algae growth, as well as corrosion to piping systems. Designed as a more accurate alternative to chemical test kits, the HI706 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, Environmental, Education, Aquariums
