Marine (dKH) Alkalinity Checker® HC - HI772

All prices are VAT excluded and without shipping costs, unless otherwise stated.

The Hanna Marine Alkalinity (dKH) 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 absorbance and ion concentration. This level of instrumentation also offers greater resolution and accuracy, but can cost hundreds of dollars. The Hanna Marine Alkalinity Checker® measures alkalinity in dKH units, using a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.

Details

The HI772 Checker®HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure alkalinity in degrees of calcium hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity. Designed as a more accurate alternative to chemical test kits, the HI772 provides quick, accurate results in four easy steps:
