With increasing temperature the specific gravity decreases. Therefore, the measured water temperature should be 25 °C \/ 77 °F to obtain a correct result.For an exact, reliable measure of the specific gravity, we recommend to use the \u003cspan\u003eTropic Marin® High Precision Hydrometer\u003c\/span\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e​\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eFill the measuring cylinder with maximum 400 ml saltwater (water temperature = 25 ° C \/ 77 °F).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eThe hydrometer should be dry and clean.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eGently place the hydrometer into the water until it floats freely.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eNow read the specific gravity on the \u003cspan\u003eblue\u003c\/span\u003e part of the scale of the hydrometer at the level of the water surface - NOT at the level of the meniscus, which is creeping higher at the edges!\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTo avoid any distortion of future measurements, rinse the measuring cylinder well with fresh tap or reverse osmosis water to remove salt residues after each use.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDO NOT CONFUSE\u003c\/span\u003e: The “\u003cspan\u003eTropic Marin® Aräometer\u003c\/span\u003e”, which is used in German speaking countries, has a scale with a green printing and the indication \u003cspan\u003e‘Dichte\/density’\u003c\/span\u003e.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eWe recommend different salinities for various tank types:\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cfigure\u003e\u003cimg src=\"https:\/\/championlightingdealer.com\/media\/wysiwyg\/Tropic_Marin_Hydrometer2.png\" alt=\"\" title=\"\"\u003e\u003cimg src=\"https:\/\/championlightingdealer.com\/media\/wysiwyg\/Tropic_Marin_Hydrometer2.png\" alt=\"\" title=\"\"\u003e\u003c\/figure\u003e\n\u003c\/div\u003e\u003c\/div\u003e","brand":"Tropic Marin","offers":[{"title":"Default Title","offer_id":67799999283496,"sku":"TMHY","price":40.31,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/6293\/4824\/files\/tropic_marin_hydrometer1.png?v=1790888090","url":"https:\/\/bubbleflowaquatix.com\/products\/tropic-marin-hydrometer","provider":"Bubble Flow Aquatix","version":"1.0","type":"link"}
