Excessive amounts of Nitrates in a reef aquarium can promote the growth of undesirable organisms including algae and dinoflagellates while insufficient amounts can lead to starvation in which SPS and other corals will show signs including the loss of color and paleness. The HI781 Nitrate Checker HC is a handheld colorimeter that uses the Beer-Lambert principle to determine the concentration of nitrate colorimetrically. The HI781 is designed specifically to measure low levels of nitrate in a saltwater aquarium. The 0.00 to 5.00 ppm (mg\/L) range is ideal for reef aquarium maintenance.\u003c\/p\u003e\n\u003cp\u003eDesigned as a more accurate alternative to chemical test kits, the HI781 provides quick, accurate results in four easy steps:\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/checker1234.jpg\" alt=\"How to use Hanna Checker Handheld Colorimeter\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\n\u003ch5 style=\"margin-top: 0;\"\u003eFeatures at-a-glance:\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eEasier to use and more accurate than chemical test kits\u003c\/li\u003e\n\u003cli\u003eSmall size, big convenience\u003c\/li\u003e\n\u003cli\u003eIdeal for aquariums and marine biology\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eHI781\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eMarine Low Range Nitrate Checker HC - HI781\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNitrate Range\u003c\/td\u003e\n\u003ctd\u003e0.00 to 5.00 ppm (as NO\u003csub\u003e3\u003c\/sub\u003e\u003csup\u003e–\u003c\/sup\u003e)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNitrate Resolution\u003c\/td\u003e\n\u003ctd\u003e0.01 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNitrate Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.25 ppm ±2% of reading @ 25 °C (77 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNitrate Method\u003c\/td\u003e\n\u003ctd\u003eColorimetric method.
