Hanna Checker Marine Ultra Low Range Nitrite Colorimeter HI764

Quick Overview

Stop struggling to get accurate results for your saltwater aquarium with our simple handheld colorimeter.


Our nitrite colorimeter fills the gap between nitrite test kits and advanced instrumentation. Standard test kits have limited accuracy since 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 nitrite result.
