measurement. The balance remembers the recently inserted data
(liquid, temperature), which shortens the measuring procedure
considerably.
18.8 Density of liquid
Density of liquid
function enables determination of any liquid density.
Using this function requires an additional kit for density determination (optional
equipment). It is the same kit like for determination of solids density (description
above).
Settings for button shortcuts are the same as for function
(see the previous point).
18.8.1. Density of liquids determination
The basic element for measuring the density of liquids is the sinker (9). Its volume
is precisely determined and given on a sinker’s hanger. Before starting liquid
density determination, insert the value of sinker’s volume to balance memory. In
order to measure the density of liquid, first determine mass of the sinker in the air.
Then, measure mass of the same sinker in tested liquid. The result of liquid density
determination is automatically indicated on balance display.
In order to determine the liquid density you need to:
1. Instal the density determination kit,
2. Enter function
3. Prepare a sample,
4. Initiate the process (like in case of solids density determination),
5. Insert the settings for the process following the displayed messages,
6. Volume of the sinker used for measuring
