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:
The Marine Alkalinity (dKH) Checker® HC Calibration Check Set – HI772-11 provides a simple solution to validating the Marine Alkalinity Checker® HC – HI772 that has a range of 0.0 to 20.0 dKH. Thishigh-qualityy set of standards is manufactured in our state-of-the-art facility and comes supplied with a Certificate of Analysis. The Certificate of Analysis provides the lot number, reference values and expiration date for traceability when certifying the Checker®HC.
The HI772-26 are the replacement reagents for the Marine Alkalinity (dKH) Checker® HC – HI772. These high-quality reagents are manufactured in Hanna Instruments state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.
