Abstract
A hydrometer includes a liquid container defining a measuring chamber. A pointer is pivotally mounted inside the measuring chamber and adapted for indicating the specific gravity of a liquid sample contained in the measuring chamber. The liquid container is mounted with a concealed liquid sample intake pipe adapted for picking up the liquid sample to be measured and delivering the liquid sample to the measuring chamber. The concealed liquid sample intake pipe has a bottom open end extending out of the lowest side of the liquid container and a top open end suspending in the measuring chamber above the upper limit liquid level.
Claims1
A hydrometer comprising a liquid container, said liquid container having a handle at a top side thereof, and a measuring chamber at a bottom side thereof for containing a liquid sample to be measured and having an upper limit liquid level defining an upper limit at which the measuring chamber may contain the liquid sample, and a pointer pivotally mounted inside said measuring chamber for indicating the specific gravity of the liquid sample contained in said measuring chamber, wherein said liquid container comprises a concealed liquid sample intake pipe, having a bottom open end extending out of the lowest side of said liquid container and a top open end located in said measuring chamber above said upper limit liquid level, for picking up the liquid sample to be measured at the bottom open end and delivering it to said measuring chamber through the top open end.
