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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures at-a-glance:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEasier to use and more accurate than chemical test kits\u003c\/li\u003e\n\u003cli\u003eDedicated to a single parameter\u003c\/li\u003e\n\u003cli\u003eSmall size, big convenience\u003c\/li\u003e\n\u003cli\u003eIdeal for: Aquaculture, Water Quality, Environmental, Education\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eNever 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.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRange: 200 to 600 ppm\u003c\/li\u003e\n\u003cli\u003eResolution: 1 ppm\u003c\/li\u003e\n\u003cli\u003eAccuracy @ 25°C\/77°F: ±6% of reading\u003c\/li\u003e\n\u003cli\u003eLight Source: LED @ 610 nm\u003c\/li\u003e\n\u003cli\u003eLight Detector: silicon photocell\u003c\/li\u003e\n\u003cli\u003eMethod: adaptation of the Zincon method\u003c\/li\u003e\n\u003cli\u003eEnvironment: 0 to 50°C (32 to 122°F); RH max 95% non-condensing\u003c\/li\u003e\n\u003cli\u003eBattery Type: (1) 1.5V AAA\u003c\/li\u003e\n\u003cli\u003eAuto-off: after ten minutes of non-use\u003c\/li\u003e\n\u003cli\u003eDimensions: 81.5mm x 61mm x 37.5mm (3.2\" x 2.4\" x 1.5”)\u003c\/li\u003e\n\u003cli\u003eWeight: 64 g (2.25 oz.)\u003c\/li\u003e\n\u003cli\u003eWarranty: 1 year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hanna","offers":[{"title":"Default Title","offer_id":46714341327000,"sku":"HI758","price":77.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0616\/0950\/9016\/files\/hi758-checkerhc-front-_2.jpg?v=1750273002","url":"https:\/\/thepetsource.ca\/products\/hanna-checker-saltwater-aquarium-calcium-colorimeter-hi758","provider":"The Pet Source","version":"1.0","type":"link"}
