* place the hydrometer gently into the sample at least 0.5 in.
* allow the hydrometer to settle for one minute before reading the gage value;
Balling: The Balling hydrometer
scale was developed by a German chemist in 1843 to measure the concentration of a sucrose solution.
The earliest - and still common - use of this principle was in the hydrometer
. Basically, a hydrometer
uses a discovery by Archimedes more than 21 centuries ago: It's possible to determine a liquid's density by floating and weighing a solid object in it.
The low-resolution plastic Baume hydrometers
were selected and used in the experiments to represent the typical foundry hydrometer
However, there is a potential for high operator variability with hydrometer
testing and test parameters must be controlled.
Run and Drip--Run and drip viscosity is measured by removing a hydrometer
from the coating, holding it at a [45.sup.[omega]] angle and observing the way the coatings run off (stream, drip or a combination of both).
