EXPLORER BALANCES
EN-61
4.10 Density
Determination
The Explorer can be used to determine an object’s density. Four types of density determination can be made:
1. Solids
more
dense than water
2. Solids
less
dense than water
3. Liquid
density
4. Porous material (impregnated with oil)
A density determination kit is designed to be used with Ohaus Explorer balances. Illustrations in this procedure
refer to the density kit. However, you may use whatever lab apparatus that suits the requirements for density
measurements. The balance software includes a built-in reference density table for water at temperatures
between 10°C and 30°C. Review this entire section before attempting density measurements.
When making density measurements the material should weigh at least 10 mg on an analytical balance and 100
mg on a precision balance.
Density can be determined
manually
(with a key press after each step) or
automatically
(weights are
automatically recorded). Before making density measurements, establish the Application Settings.

button.
The balance calculates water density based on the water
temperature value entered (internal lookup table).
Measure the actual water temperature using a precision
thermometer.
