Hanna Calcium Checker HI758 - Marine

The HI758 Calcium Checker provides a simple, accurate and cost-effective way to measure calcium in saltwater aquariums. Required for the development of calcium carbonate skeletons of coral reefs, calcium is a crucial component of marine waters. Designed as a more accurate alternative to chemical test kits, the HI758 provides quick, accurate results in a few easy steps.

This saltwater calcium colorimeter fills the gap between calcium test kits and advanced instrumentation. Standard test kits have limited accuracy as they depend on the human eye to determine colors. Our handheld colorimeter eliminates the trouble of matching to a color chart by providing a direct saltwater calcium result in ppm Ca2+.
