Operation
Measurement Procedure
The sample weight must be determined in the air .
Procedure
Tare the balance .
t
Place the sample on the frame weighing pan and weigh it .
t
Make a note of the weight value W (a) .
t
Determining the Buoyancy
G = W (a) – W (fl)
Procedure
Tare the balance with the sample on the frame weighing pan .
t
Place the sample in the sample holder . Remove the iron pan from the measuring
t
device and ensure that no additional air bubbles become attached upon
re-immersion in the liquid; If possible, add the sample directly using tweezers or
similar .
Make a note of the absolute value of buoyancy G, with a minus sign in front .
t
Calculating the Density
Procedure
Read off the temperature .
t
Locate the density value ρ (fl) in the table in Chapter "5 .4 Density Values,"
t
page 22 using the temperature you have read off .
Calculate the density using the following formula:
t
W (a) and G in g; ρ (fl) in g/cm

W (a) · ρ (fl)
+ 0.0012 g/cm
ρ =
0.99983 G
G = W (a) – W (fl)
