hydrometer    音标拼音: [hɑɪdr'ɑmətɚ]
n. 液体比重计,浮秤

液体比重计,浮秤

hydrometer
n 1: a measuring instrument for determining the specific gravity
of a liquid or solid [synonym: {hydrometer}, {gravimeter}]

Hydrometer \Hy*drom"e*ter\, n. [Hydro-, 1 -meter: cf. F.
hydrom[`e]tre.]
1. (Physics) An instrument for determining the specific
gravities of liquids, and thence the strength spirituous
liquors, saline solutions, etc.
[1913 Webster]

Note: It is usually made of glass with a graduated stem, and
indicates the specific gravity of a liquid by the depth
to which it sinks in it, the zero of the scale marking
the depth to which it sinks in pure water. Extra
weights are sometimes used to adapt the scale to
liquids of different densities.
[1913 Webster]

2. An instrument, variously constructed, used for measuring
the velocity or discharge of water, as in rivers, from
reservoirs, etc., and called by various specific names
according to its construction or use, as {tachometer},
{rheometer}, {hydrometer}, {pendulum}, etc.; a current
gauge. Hydrometric

HYDROMETER. An instrument for measuring the density of fluids; being
immersed in fluids, as in water, brine, beer, brandy, &c., it determines the
proportion of their densities, or their specific gravities, and thence their
qualities.
2. By, the Act of Congress of January 12, 1825, 3 Story's' Laws U. S.
1976, the secretary of the treasury is authorized, under the direction of
the president of the United States, to adopt and substitute such hydrometer
as he may deem best calculated to promote the public interest, in lieu of
that now prescribed by law, for the purpose of ascertaining the proof of
liquors; and that after such adoption and substitution, the duties imposed
by law upon distilled spirits shall be levied, collected and paid, according
to the proof ascertained by any hydrometer so substituted and adopted.

  • The Great Gravity Showdown - Hydrometer vs. Digital Hydrometer vs . . .
    Anton Paar Digital Hydrometer: The Anton Paar DMA35v4 Digital Hydrometer is the simplest option I tested It requires only ~2-3ml of wort to take a reading, and doesn't require the use of a refractometer calculator post fermentation It's incredibly portable, easy to use, and stores readings in its internal memory when testing multiple batches
  • help a total noob out. . . how do you read hydrometers?
    The scale goes from 0 to 30 on most hydrometers If your wort reads 10 on the Plato scale, it contains 10% sugar by weight How accurate is you hydrometer, and how good a job are you doing at reading it? If you float you hydrometer in distilled water at 60o and Specific Gravity reads "1 000" you both both passed the test

    Does anyone have a temperature correction formula for hydrometer I found this one but its not working when I check against the tables I've found
  • Beginners!! Hydrometer reading near 0?! - Homebrew Talk
    Your and my hydrometer both come with three scales; Brix, specific gravity, and potential alcohol by weight Anyhow, upon reflection, a Brix reading of 33 ~= a sg reading of 1 140 ~= 18 5% potential alcohol which is probably every bit as impossible as your reading of "near zero" (I think you meant near 1 000) So my comment wasn't useful
  • Hydrometer dropped like a rock - Homebrew Talk
    If you have a triple scale brewing hydrometer, the % scale is used to estimate the amount of alcohol in the finished product So if your beer starts at the 6% mark and stops at the 1% mark, the alcohol content is about 5% If there is only one % scale it might a hydrometer for measuring salinity or antifreeze solutions
  • Hydrometer floats too high in the sample - Homebrew Talk
    A proof and tralle hydrometer is used for testing the alcohol content of distilled spirits Scales: Proof: 0-200 Tralle: 0-100 This proof tralle scale determines the direct percentage of alcohol in liquids with a specific gravity less than zero Just put a sample of unsweetened liquid containing alcohol in a test jar and float the hydrometer in the liquid The hydrometer is fragile so stay

  • Reading a hydrometer - confused - Homebrew Talk
    What's the correct way to read a hydrometer? This website - Stevenson Reeves - How to use a hydrometer - says: The correct scale reading is that corresponding to the plane of intersection of the horizontal liquid surface and the stem This is not the point where the surface of the liquid
  • Hydrometer Reading - very confused - Homebrew Talk
    Some weight on the hydrometer, bubbles under the hydrometer, the hydrometer touching the side, the paper slipped down (likely), etc The reading is wrong The original reading is wrong as well, and it seems that both readings are too low The hydrometer should be floated in plain water, to see how far off it is
