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. Our handheld colorimeter eliminates the trouble of matching to a color chart by providing a direct saltwater calcium result in ppm Ca2+.
- Our portable handheld colorimeter goes where you go.
- Achieve your calcium results easily with simple, one-button design.
- Quickly get your results without any hassle.
