Hanna Marine Alkalinity (dKH) Checker® HC – HI772
The HI772 Checker® HC (Handheld Colorimeter) provides a simple, accurate, and cost-effective way to measure alkalinity in degrees of carbonate hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion concentration required for skeletal formation and growth of many coral, but also acts as a pH buffer against large changes in acidity.
Hanna Marine Calcium Checker® HC – HI758U
The HI758U Checker® HC (Handheld Colorimeter) provides a straightforward way to measure calcium. Required for the development of calcium carbonate skeletons of coral reefs, calcium is a crucial component of marine waters. Accurately testing calcium levels is critical for everyone from coral reef hobbyists to aquaculture farms and research facilities. Updated to include the HI731339p mechanical pipette for better accuracy.
Marine Phosphate Ultra Low Range Colorimeter – HI774
The HI774 Ultra Low Range Phosphate Checker® HC (Handheld Colorimeter) is a cost-effective way to measure phosphate in marine systems, including reef tanks. Testing for phosphates is standard practice for saltwater aquariums and provides valuable insight into your reef tank’s water chemistry to help ensure long-term coral health. Phosphates are one of the many forms of phosphorus compounds found in marine waters. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp stony. In addition, high phosphate levels can cause nuisance algae growth in your reef tank. This can become problematic because algae often outcompetes sessile organisms for light, nutrients, and space, jeopardizing long term coral health in your reef.
Marine Salinity Tester – HI98319
Designed to bring simplicity to salinity testing during the any process, the HI98319 Marine Salinity Tester measures conductivity (EC) to determine the salinity of natural and artificial seawater. Within seconds, the salinity and temperature are digitally displayed on the LCD.
