In DENSITY SETUP, set Mode to Liquid Density and enter sinker volume in cc's.
After weighing the sinker in air and then weighing the sinker immersed in liquid, the balance calculates the density
of the liquid and is displayed in grams/cc. See illustrations below for placement of the sinker. When the sinker is
immersed in the liquid, it must not come into contact with the bottom of the beaker.
Porous Material Density Determinations
The density of a porous (oil impregnated part) can be made with the balance. Weigh the part (dry) prior to oil
impregnation and record its weight. You must also know the density value of the oil to be used in immersing the
part before starting. In this procedure, you will follow the method for solid density measurements using water.
Enter the dry weight of the porous material and the density of oil used to impregnate the part.
To Determine Wet Density
Wet density of the sample can be calculated by following the normal Solid Density procedure using the oil
impregnated part.
Before density measurements can be made, the density mode of operation must be set up in the Menu, Mode Sub-
menu. It is in the Mode Sub-menu where solid, porous, water or auxiliary liquids are selected.
After the basic parameters have been set, the balance density operation is further determined in the APPL
DENSITY menu. This menu allows the setting of Density, Temperature, Dry Weight of Porous Material, Sinker
Volume and Density of Oil.
Operation Method
Press and hold the Function / Mode button until the Density appears on the screen.
After confirmation by pressing Yes, the message "Change parameter?" will display on the screen. The settings
can be kept or changed as desired.
Item Settings:

Sample Type: Solid, Liquid

Auxiliary Liquid: Water, Alcohol, Other

Porous Material: Off, On

Water Temperature: 20℃ (by default)

Alcohol Temperature: 20℃ (by default)

Volume (of Calibrated Sinker): 10 ml (by default)

Weight (of Porous Material): 5.000 g

Oil Density: 0.80000 g / cm
Four types of density determination can be made:
1. Solid more density than the auxiliary liquid
2. Solid less density than the auxiliary liquid
3. Liquid density
4. Porous material (impregnated with oil)
The following are the operating procedures for determining density of solid, liquid and porous material with water
as the auxiliary liquid. Other auxiliary liquids are also applicable for density determination.
