The HI783 Marine Magnesium Checker HC is a handheld colorimeter that uses the Beer- Lambert principle to determine the concentration of magnesium colorimetrically. The HI783 is designed specifically to measure magnesium levels in a saltwater aquarium or in marine biology applications. The 1000 to 1800 ppm range is ideal for coral/fish or fish-only aquarium maintenance. Ideal for aquariums and marine biology Easier to use and more accurate than chemical test kits Small size, big convenience Magnesium is the third most abundant ion in seawater, surpassed only by sodium and chloride. Its abundance is critical in the formation of weak ion pairs with carbonate ions. This allows calcium and carbonate ions to be available for uptake by corals and invertebrates. Low levels of magnesium lead to low or unstable levels of calcium and alkalinity. Signs of low magnesium levels include precipitation of calcium as insoluble calcium carbonate and impaired inhabitant growth and health. SKU HI783 Name Marine Magnesium Checker HC Handheld Colorimeter – HI783 Range 1000 to 1800 ppm Magnesium Resolution 5 ppm Accuracy ?5% of reading @ 25 ?C (77 ?F) Light source Light Emitting Diode @ 610 nm Light detector Silicon photocell Method Adaptation of the colorimetric EDTA method using calmagite indicator. The reaction between magnesium and the reagents causes a blue to violet tint in the sample. Environment 0 to 50 ?C (32 to 122 ?F); max. 95% RH non-condensing Prepared sample cuvette (sample plus reagents) must be 18 to 28 ?C (64 to 82 ?F).

Product information "HI758 Marine Calcium 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. 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. Details 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. 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.   Specifications Range 200 to 600 ppm Resolution 1 ppm Accuracy @ 25°C/77°F ±6% of reading Light Source LED @ 610 nm Light Detector silicon photocell Method adaptation of the Zincon method Environment 0 to 50°C (32 to 122°F); RH max 95% non-condensing Battery Type (1) 1.5V AAA Auto-off after ten minutes of non-use Dimensions 81.5mm x 61mm x 37.5mm (3.2" x 2.4" x 1.5”) Weight 64 g (2.25 oz.)
