Saltwater Aquarium Calcium Colorimeter - Checker® HC

Always get accurate results for your saltwater aquarium with our handheld colorimeter.

Our 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.
