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.
