In making tests with the hydrometer, the electrolyte should always be returned to the same cell from which it was drawn.
The rubber tubing on the hydrometer should not be withdrawn from the cell.
Have we not reason to think that on this occasion the hydrometer must have occurred to him had it been then used?
The first is that the readings taken with a hydrometer will then be misleading.
The instruments used in obtaining the results were a thermometer and a hydrometer.
It indicates the strength and is measured by the hydrometer.
If no sugar is in the water, the reading on the hydrometer will be near zero.
A hydrometer that is especially adapted to milk is called a lactometer.
The hydroscopium was undoubtedly a hydrometer of the simplest construction.
Let us suppose the hydrometer indication to be 430, the weight per imperial gallon would be 8903 lbs.
hydrometer hy·drom·e·ter (hī-drŏm'ĭ-tər)
An instrument used to determine specific gravity, especially a sealed graduated tube, weighted at one end, that sinks in a fluid to a depth indicating the fluid's specific gravity. Also called gravimeter.
An instrument used to measure the density of a liquid as compared to that of water. Hydrometers consist of a calibrated glass tube ending in a weighted glass sphere that makes the tube stand upright when placed in a liquid. The lower the density of the liquid, the deeper the tube sinks.
