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

The Hanna Calcium Colorimeter - Checker® HC (HI758) 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. This handheld colorimeter eliminates the trouble of matching to a color chart by providing a direct saltwater calcium result in ppm Ca2+.

  • Goes where you go.
  • Achieve your calcium results easily with simple, one-button design.
  • Quickly get your results without any hassle.

The HI758U Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure calcium. 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 HI758U provides quick, accurate results in a few easy steps.

Features at-a-glance

  • Easier to use and more accurate than chemical test kits
  • Dedicated to a single parameter
  • Small size, big convenience
  • Ideal for: Aquaculture, Water Quality, Environmental, Education

The HI758U Marine Calcium Checker HC® uses a 100 to 1 dilution for analysis and thus requires deionized or distilled water absent of calcium to function correctly. Calcium can be found in many freshwater sources and this any amount present in the water used at the C1 phase can cause false high readings. In addition, many hobby grade reverse osmosis deionized water systems may not adequately remove calcium. This can vary based on the types of filters used, their effectiveness and frequency of replacement. It is recommended to use deionized water with low conductivity or pure vapor distilled water commonly found in most pharmacies.

Never use tap water to clean your cuvettes. This is especially important for the HI758U Marine Calcium Checker as calcium is commonly present in tap water and residual amounts present in the cuvette will elevate results produced by the Checker.
