The Hanna Nickel 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 Nickel 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
The HI726 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure nickel. Commonly used by both the electroplating and battery industries, nickel is actively monitored in wastewater due to damage it can cause to plants and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI726 provides quick, accurate results in four easy steps:
Easier to use and more accurate than chemical test kits
Dedicated to a single parameter
Small size, big convenience
Ideal for: Water Quality, Environmental, Industrial
