Web16 Dec 2024 · Many hydrometers are calibrated to a solution temperature of 15° C or 60° F. Improving Accuracy Accuracy depends on three main factors: Cleanliness: The … WebThe technique uses a hydrometer which is probably calibrated to read %ABV at 20 C. So you need to find an equation for the density of an ethanol-water mixture as a function of ethanol concentration and temperature. – MaxW Feb 5, 2024 at 22:57 2 brother justio fax-2840 説明書

WebThermo Fisher Scientific Web1 Feb 2024 · I am guessing your hydrometer is pretty close as the online calculators still say a hydrometer calibrated to 77 F and reading a solution at 18 C at 1.0284 would give a reading of 1.027 which is pretty darn close to 1.0264 So if anything it's reading around 0.0006 high. edit. ok so it's about 0.0004 high then?
