11.9.1. Density Determination
The basic element for measuring liquids density is the sinker (9). Its volume is precisely determined
and given on a sinker’s hanger. Before starting liquid density determination, enter sinker’s volume
value to the 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 the 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. Install the density determination kit.
2. Enter <LIQUIDS DENSITY> function.
3. Prepare a sample.
4. Initiate the process.
5. Set the process following the displayed messages.
6. Set volume of the sinker used for measuring.
7. On entering the data, the software proceeds to weighing.
8. First, place the sinker on the hook (a sample mass determination in the air), and confirm the
indication when stable.
9.
Next, take the sinker out of the hook, put the beaker with liquid on the beaker’s basis (the
beaker cannot touch the hook), gently hang the sinker on the hook providing that it is totally
immersed in the tested liquid (sample mass determination in liquid) – and confirm the indication
when stable
.
10. On the second confirmation of the indication, the program automatically calculates and displays
the tested solid object density. At the same time, a report on the measurement is sent to a
selected port of a printer.
