{"product_id":"marine-magnesium-checker-hc-handheld-colorimeter-hi783","title":"Marine Magnesium Checker HC Handheld Colorimeter - HI783","description":"\u003cp\u003eMagnesium 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 lowmagnesium levels include precipitation of calcium as insoluble calcium carbonate and impaired inhabitant growth and health.\u003c\/p\u003e\n\u003ch5\u003ePrimary Applications:\u003c\/h5\u003e\n\u003cp\u003eMarine, Saltwater Aquariums, Aquaculture\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eHI783\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eMarine Magnesium Checker HC Handheld Colorimeter - HI783\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e1000 to 1800 ppm Magnesium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e5 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±5% of reading @ 25 °C (77 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight source\u003c\/td\u003e\n\u003ctd\u003eLight Emitting Diode @ 610 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight detector\u003c\/td\u003e\n\u003ctd\u003eSilicon photocell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eAdaptation of the colorimetric EDTA method using calmagite indicator.
