{"product_id":"hygger-acrylic-aquarium-hydrometer","title":"hygger Transparent Acrylic Aquarium Hydrometer, salinity and specific gravity test, swing-arm pointer","description":"\u003cp\u003eThis aquarium hydrometer from hygger arrives with two scales built into one transparent acrylic body: specific gravity from 1.000 to 1.030 and a ppt value range of 0 to 43.9 degrees. A swing-arm pointer moves against the markings, and the wide base lets the unit stand on a level surface while you read it. The scale carries three marked bands so you can see where a reading falls before you compare it with your own target.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003ehygger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eTransparent acrylic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eScale\u003c\/th\u003e\n\u003ctd\u003eSpecific gravity 1.000-1.030; ppt value 0-43.9 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy\u003c\/th\u003e\n\u003ctd\u003e+\/-0.001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eHow the swing-arm pointer works\u003c\/h2\u003e\u003cp\u003eThe pointer swings to a position on the printed scale and stays there while the unit rests flat. Readings are temperature-corrected, and the stated accuracy is +\/-0.001. Because the housing is transparent acrylic, the scale sits behind clear material.\u003c\/p\u003e\u003cp\u003eThe face is divided into three marked areas. The safe area runs from specific gravity 1.020 to 1.023, which corresponds to a ppt value of 30.2 to 34.2 degrees. Below that, the low specific gravity area covers 1.000 to 1.019 (ppt 0 to 28.9 degrees), and the higher specific gravity area covers 1.024 to 1.030 (ppt 35.5 to 43.9 degrees).\u003c\/p\u003e\u003ch2\u003eSuits brackish and reef salt marine tanks\u003c\/h2\u003e\u003cp\u003eThis hydrometer suits brackish and reef salt marine aquariums. It measures salinity and specific gravity in those tanks rather than in freshwater setups. A buyer should confirm the tank is a marine system before relying on the two scales.\u003c\/p\u003e\u003ch2\u003eCleaning the acrylic body\u003c\/h2\u003e\u003cp\u003eAfter use, soak the hydrometer in mild acid such as vinegar for 30 minutes, then rinse it with tap water and let it air dry. The transparent acrylic housing is the part that goes into the soak and rinse.\u003c\/p\u003e\u003ch2\u003eWhat the pack contains\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eOne hydrometer with salinity and specific gravity scales printed on it\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eHow to take a reading\u003c\/h2\u003e\u003cp\u003eDunk the hydrometer in the aquarium so it fills with water, then set it on a level surface and read the pointer against the scale. The wide base keeps the unit steady on that surface. Both the specific gravity and the ppt scales are visible on the same face, so one reading gives you either value.\u003c\/p\u003e\u003ch2\u003eQuestions about the hygger hydrometer\u003c\/h2\u003e\u003ch3\u003eWhat specific gravity range does the scale cover?\u003c\/h3\u003e\u003cp\u003eThe specific gravity scale runs from 1.000 to 1.030.\u003c\/p\u003e\u003ch3\u003eWhat salinity range does the hydrometer read?\u003c\/h3\u003e\u003cp\u003eThe ppt scale covers 0 to 43.9 degrees.\u003c\/p\u003e\u003ch3\u003eHow accurate is the reading?\u003c\/h3\u003e\u003cp\u003eThe stated accuracy is +\/-0.001.\u003c\/p\u003e\u003ch3\u003eWhat material is the hydrometer made of?\u003c\/h3\u003e\u003cp\u003eIt is made of transparent acrylic.\u003c\/p\u003e\u003ch3\u003eHow do I clean it after testing?\u003c\/h3\u003e\u003cp\u003eLeave it to soak 30 minutes in a mild acid like vinegar, then rinse it under tap water and let it air dry.\u003c\/p\u003e","brand":"hygger","offers":[{"title":"Default Title","offer_id":44474279034943,"sku":null,"price":31.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/2409\/1199\/files\/hygger-aquarium-hydrometer.jpg?v=1794652682","url":"https:\/\/dogjointly.com\/products\/hygger-acrylic-aquarium-hydrometer","provider":"DogJointly","version":"1.0","type":"link"}
