Hydrometers are used to test the state of charge of a battery cell.\nThis is performed by measuring the density of the electrolyte, which is\naccomplished by measuring the specific gravity of the electrolyte. The greater\nthe concentration of sulfuric acid, the more dense the electrolyte becomes.\nThis high quality hydrometer includes a built in thermometer that indicates\nthe correction factor - based on specific temperatures - that must be added or\nsubtracted from the float reading to arrive at an accurate specific gravity\nreading for each battery cell. Features glass and rubber construction with a\nflexible tip that offers easy access to even hard to reach battery cells while\nthe battery is still in the vehicle. One year limited warranty. Value is at\nthe core of the OTC tool and equipment portfolio. For a simple repair or the\nmost complex drivability concern, these award-winning tools universally solve\nproblems faster, and at better value, than any other product line available.\nWhether it’s a specialty tool or unique piece of service equipment, OTC\nprovides top solutions to modern automotive service challenges while\nincreasing technicians’ productivity and shop profits.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eHydrometers test the state of charge of a battery cell by measuring the specific gravity (density) of the electrolyte - the greater the concentration of sulfuric acid, the more dense the electrolyte becomes\u003c\/li\u003e\n         \u003cli\u003eOTC's Professional Battery Hydrometer displays a batteries specific gravity (density) on an easy-to-read float with a scale ranging from 1.100 to 1.300\u003c\/li\u003e\n         \u003cli\u003eBuilt in thermometer indicates what must be added or subtracted from the float reading to arrive at an accurate specific gravity reading for each battery cell\u003c\/li\u003e\n         \u003cli\u003eFlexible rubber tip offers easy access to even hard to reach battery cells while the battery is still in the vehicle\u003c\/li\u003e\n         \u003cli\u003eGlass and rubber construction; One year limited warranty\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"OTC","offers":[{"title":"Default Title","offer_id":45784785551429,"sku":"B0050SFVHO","price":160.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0281\/4174\/8293\/files\/B0050SFVHO.jpg?v=1789623969","url":"https:\/\/beesactive.com\/products\/otc-4619-professional-battery-hydrometer","provider":"BeesActive Australia","version":"1.0","type":"link"}
