Hydrometers are standardized to 59°F (15°C), and when used in a sample at any other temperature, the observed reading must be corrected. Tilt will stay on within an SG range of 0.990 - 1.200. 687 0 obj <>stream Q. Percent Finer (assume ρs = 2.65 g/cm3) % = ×100 s c W aR Finer (5) where; Rc = corrected hydrometer reading (g/1000ml) Ws = original dry mass (g) a = correction factor for particle density (a = 1.00 for 2.65g cm3 range 1.038-1.050 and for a wine, around 1.075-1.095. Our customers are not only the scientific community but also hobbyists, artists, schools and universities. Vineyards use this scale to determine if the sugar level of the grape is sufficient for harvest. The scale on these Hydrometers indicates the "Specific Gravity" of the liquid. Hydrometers used for brewing will tell you the specific gravity of a liquid - a ratio of the liquid's density to that of water. 0000011007 00000 n Alcohol (Tralle and Proof Scales) hydrometers measure directly in percentage ethyl alcohol by weight in water from 0 to 100%. http://alcoholcontrols.com/lihy.htmlThis popular 11" hydrometer is designed to test the alcohol volume in distilled spirits. 0000013960 00000 n 0000018619 00000 n Hydrometers are instruments that work on the principles of buoyancy and liquid displacement (MEBAK, 2013).

Most homebrew hydrometers are calibrated at 59–60°F (15–15.6°C ), and most laboratory hydrometers are calibrated at 68°F (20.0°C). 0000003612 00000 n A good hydrometer is accurate to +/- 0.005 points so 1.265 could read from 1.260-1.270. 0000013450 00000 n A hygrometer is an instrument used to measure the amount of water vapor in air, in soil, or in confined spaces. 0000014044 00000 n 0000006819 00000 n A range of saccharometers, hydrometers, hydrometer jars and accessories A range of pH meters and accessories A range of refractometers with sugar scales A range of volumetric glassware for lab and bottling, along with dip rods and tapes for large vessels A range of liquid in glass thermometers and digital thermometers . Fisher Scientific, Bishop Meadow Road, Loughborough, Leicestershire, LE11 5RG © Fisher Scientific UK Ltd All rights reserved. Hydrometers can lose accuracy over time. Step 2: To determine how much additional sugar is necessary to bring the must to the desired SG (let's say 1.090), use the chart below. Our Price: (Registered Users Only) Thermohydrometer: 59-71 API, 0-150 F, 380mm, ASTM S557HL (non-mercury) Non Mercury Fuel Type Thermohydrometer, 57HL, 59-71 API for more information see Bulletin No.61. Baume Range: 1 to 1.22: For Use With (Application) Measure true specific gravity of liquids heavier than Water: Increments: 0.002: Product Type: Specific Gravity Hydrometer: Subdivisions: 0.002: … The hydrometer should give you a numeric reading directly from the instrument. If you consult the … Take a reading, then refer to the hydrometer chart below. 0000005788 00000 n Using the calculator below, enter the temperature of the sample and the observed standard gravity reading to obtain the corrected standard gravity (SG). CARBONATION TESTERS 37 - 40 SAMPLING EQUIPMENT 43 - 46 COOPERAGE … A hydrometer with a narrow range of specific gravity between .990-1.020 lets you see exactly when your beer has finished fermenting. Scales have clearly marked figures and graduations. It is usual for hydrometers to be used with dense liquids to have the mark 1.000 (for water) near the top of the stem, and those for use with lighter liquids to have 1.000 near the bottom. 0000003841 00000 n A specific gravity of 1.048 is equivalent to 12 ° Plato. If you're using an old tool, you may want to test it first . Narrow range hydrometers are specialized tools to measure specific gravity with high degrees of accuracy.
