## Overview

The Hanna HI772 is a handheld colorimeter designed for precise, quick measurement of alkalinity in saltwater aquariums. Compact and portable, it offers user-friendly operation with batteries included, delivering reliable dKH readings essential for coral reef health and marine biology applications.

## 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.

Manual alkalinity tests are a pain the butt, and are so easy to mess up and get inaccurate results. This Hanna checker is worth the buy. Testing is so easy and fast, and you can rely on the results.
