EN-18 Ohaus Discovery
3.5.9 Density
Refer to section 3.7.5 to enable density measurements. Follow the procedures as indicated after initial setup in Section 3.7.5. Read the infor-
mation concerning density measurements after the procedure which references an Ohaus Kit used specifically for density measurements.
Four methods of density determinations can be made with the Discovery balance. These are:
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 Part Number 80850045 is designed to be used with Ohaus Discovery balances. Illustrations in this procedure refer
to the density kit, however, you may use whatever lab apparatus that will suit the requirements for density measurements. A built in reference
density table for water at temperatures between 10ºC and 30ºC is included in the balance software. Review this entire section before attempting
density measurements.
When making density measurements, the material should weigh at least 10.0 mg on an analytical balance and 100 mg on a precision balance.
Balance Preparation with Ohaus Density Kit (Optional)
Allow the balance to warm up sufficiently before making mea-
surements.
Open either the left or right side door of the balance and remove
the Pan as shown. Insert the Bracket into the balance where the
Pan was removed.
The Equalizing Washer is not used.
