Phosphate is an important parameter to measure in aquaculture and aquariums; levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI774 provides quick, accurate results. For those that would like measure phosphate as phosphorous we off the HI736 Phosphorous Checker® HC. Alternatively, to determine the fraction of phosphorous (PO\u003csub\u003e4\u003c\/sub\u003e-P) there is in phosphate (PO\u003csub\u003e4\u003c\/sub\u003e\u003csup\u003e3-\u003c\/sup\u003e) the phosphate reading is multiplied by 0.3261. A 0.50 ppm phosphate reading is equal to 0.163 ppm or 163 ppb phosphorous.\u003c\/p\u003e\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\u003ch4 style=\"margin-top: 0;\"\u003eFeatures at a Glance\u003c\/h4\u003e\n\u003ch5\u003ePre-mixed Chemistry\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eReagents are pre-measured packets that are added to the sample to take a reading.\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch5\u003eColorimetric Readings\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eUsing an LED at a specific wavelength and silicon photo detector the HI774 can perform a precise reading of the color change in the sample based on the phosphate concentration.\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch5\u003eChecker HC Calibration Standards\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe HI774-11 CAL-Check standards can be purchased separately and are used to check the performance of the meter to ensure confidence that the meter is working properly.\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch5\u003eAutomatic Shut-off\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe meter is programmed to turn off after seven minutes of non-use or two minutes after taking a reading.\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch5\u003eLong Battery Life\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe phosphate ULR Checker has an exceptional battery life with a fresh battery lasting for a minimum of 5000 measurements.\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch5\u003ePlastic Carrying Case\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe 774 is supplied complete with meter and reagents for 10 tests that are packaged in a durable plastic carrying case.\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch5\u003eEconomical\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eLaboratory grade measurements at a cost of a chemical test kit.\u003c\/li\u003e\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\u003eHI774\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eMarine Phosphate Ultra Low Range Checker\u003csup\u003e®\u003c\/sup\u003e HC - HI774\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhosphate Range\u003c\/td\u003e\n\u003ctd\u003e0.00 to 0.90 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhosphate Resolution\u003c\/td\u003e\n\u003ctd\u003e0.01 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhosphate Accuracy\u003c\/td\u003e\n\u003ctd\u003e± 0.02 ppm ± 5% of reading\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhosphate Method\u003c\/td\u003e\n\u003ctd\u003eadaptation of the Standard Methods for the Examination of Water and Wastewater, 20\u003csup\u003eth\u003c\/sup\u003e edition, Ascorbic-Acid method.
