Alkalinity Checker (up to 20.0 dKH) HI772 - HANNA
Description
Le (The) Hanna Seawater Alkalinity (dKH) Checker® is a good compromise between the choice of simple chemical test kits and professional-quality instrumentation. Chemical test kits have limited accuracy and resolution because they rely on distinguishing color differences perceived by the human eye.
Professional-grade instrumentation includes a light source composed of an LED or a tungsten lamp with a filter and a light detector to accurately determine the absorbance and concentration of ions.
Professional tools offer superior resolution and precision, but they can cost hundreds of euros. The Checker ® Hanna For Alkalinity in Seawater, it measures alkalinity in dKH and uses a fixed wavelength LED source and a silicon photoelectric cell to ensure the precision of professional instrumentation at the affordable price of a chemical test kit.
The HI772 Checker® HC (portable colorimeter) is a simple, accurate, and affordable tool for measuring alkalinity in degrees of calcium hardness, commonly abbreviated as dKH. Alkalinity is one of the most important parameters to keep under control in marine aquariums.
Helps maintain a stable pH, essential for most aquatic species. In seawater, carbonates and bicarbonates determine alkalinity and are critical elements for the health of corals.
Characteristics
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
