A graduated instrument for finding the specific gravity of liquids A hydrometer is used to determine the concentration of acid in a storage battery or to test the purity of milk, the strength of alcohol or salt in a substance, etc A hydrometer consists of a glass tube with a bulb syringe for sucking up samples of the electrolyte Within the glass tube is a calibrated float The depth to which the float sinks is a measure of the specific gravity of the solution (Dictionary of Science)
An instrument for determining specific gravity It can also be used as a grain size test, because grain size distribution affects the specific gravity of fluids according to the distribution present
A device used to measure the specific gravity of seawater The most common types consist of a clear chamber with a floating needle
a measuring instrument for determining the specific gravity of a liquid or solid
A simple device that measures the specific gravity of battery electrolyte Specific gravity readings express state of charge / discharge of battery
A long, weighted, tapered glass rod that is calibrated and floats in solutions It is used to measure density of liquids, especially silicates
instrument used to measure water salinity based on the density and specific gravity of the water
(Otomotiv) A device to determine the specific gravity of a liquid. It's used to test battery electrolyte and the percentage of coolant in the cooling system
An instrument that uses buoyancy to measure the density of a liquid; it consists of a weighted tube that floats vertically and determines the specific gravity of the liquid by a comparison of the scale on the tube with the level it floats in the liquid
A device for measuring the sugar content of beer wort, by determining its density There are several different hydrometer scales which are used; the most common one used by homebrewers is specific gravity; other commonly used scales are Plato, and potential alcohol
A float type instrument used to determine the state-of-charge of a battery by measuring the specific gravity of the electrolyte (i e the amount of sulfuric acid in the electrolyte)
An instrument made of glass used to measure the specific gravity of a liquid as compared to water The instrument consists of a graduated stem resting on a floating weight
device that compares the density of a sample with the density of water to directly indicate the alcohol content of the spirit
An instrument used to check the specific gravity (strength) of the electrolyte in the battery Most Lead-Acid batteries will be in the range of 1 1 to 1 3 specific gravity, with most fully charged batteries being about 1 23 to 1 30 (some hydrometers multiply this number by 1000, so 1 23 would read as 1230 ) Hydrometers are inexpensive and can be purchased at any auto parts store Some batteries manufactured for use in very hot or very cold climates may have stronger or weaker acid If so, it is usually marked on the battery See also Specific Gravity
