Hanna – Marine Alkalinity (dKH) Checker® HC: 0.0 to 20.0 dKH, plus 25 tests (HI-772)

The HI-772 Alkalinity Checker is designed specifically for use within saltwater and coral reef aquariums, measuring directly in dKH (degrees of calcium hardness) with no need to convert readings from ppm. This digital alkalinity tester enables you to accurately measure the calcium hardness within your marine fish tank to determine if you are in the best dKH range for your saltwater aquarium requirements. Stability in dKH is key for healthy coral growth and precipitation, helping to maintain a steady pH for a healthier tank.

Hanna Checkers are convenient, easy and fast to use, with a single-button operation and a user-friendly handheld design for the precise measurement of marine alkalinity and other key fish tank parameters.
