EJ-13 Density Determination Kit
Using this option and calculation program,
the balance can determine the density
(specific gravity) of a sample.
EJ-13 is for use with the EJ-123 / EJ-303.
EJ-13 Installation
Remove the weighing pan and the fixing
frame.
Install the beaker stand on the balance
and attach the pan stand to the pan
support of the balance.
Remove the breeze break that can not be
used while using the density
determination kit.
Place a beaker filled with water on the
beaker stand and place the sample
weighing pan on top of the pan stand.
Density (Specific Gravity) Measurement
The density for a liquid can be set two ways.
One is to set the water temperature and the
other is to set the density value directly.
The factory setting for density of a liquid is
25 °C as water temperature (the density
value,
ρ
= 0.99704 (g/cm
3
), is used for
calculation).
The result is shown with three decimal places.
The density (specific gravity) is calculated by
the following formula.
S =
x
ρ
S: Density (specific gravity) of a sample
A: Weight in air
B: Weight in liquid
ρ
: Density of liquid (water)
