## Overview

The Hanna HI772 Checker is a handheld colorimeter designed for precise, quick measurement of alkalinity (dKH) in saltwater aquariums. Its compact, portable design and simple one-button operation make it ideal for professionals and enthusiasts alike, ensuring accurate monitoring critical for coral health and marine ecosystem stability.

## Description

HI772 Hanna checker for testing in saltwater applications. The HI772 (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 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 a few easy steps.
