The Hanna Iodine 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 Iodine 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 HI718 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure iodine. Introduced as an alternative to chlorine, iodine as a sanitizer decreases eye irritation in pools and saps and provides a more stable level of disinfection in adverse conditions. However, due to its toxic and corrosive properties, iodine is strictly monitored. Designed as a more accurate alternative to chemical test kits, the HI718 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, Education, Industrial, Agriculture, Pool and Spa
