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 CaCO3.
- 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.
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. We recommend using 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. Our HI98703-50 Cuvette Cleaning
Solution ensures the glass cuvette used for colorimetric measurements
remains clean and free from imperfections.
Calcium Checker Troubleshooting Tips
- Never rinse your cuvettes with tap water or saltwater
- Use pure vapor distilled water from your local pharmacy at C1 phase.
RODI water from home filtration units may not be suitable for this test
as calcium can easily permeate through your filter membranes.
- Clean your cuvettes with distilled or deionized water absent of Calcium that is going to be used for C1 phase dilution.
- Measure out 9 ml of distilled or deionized water for C1 phase
- Make sure no excess aquarium sample saltwater is on the tip of the
pipette. Only administer the saltwater that is sucked into the pipette
tip.
