Density Determination

Note: Before using any application, be sure the balance has been leveled and calibrated.
Use this application to determine an object's density.
A Density Determination Kit, Part Number 80253384, is designed to be used with PJX
series 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 the temperature of 20º C 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 measurements.
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.
Operation Method
Two types of density determination can be made:
1. Solid more dense than the water
2. Solid less dense than the water
Note: It is required that the auxiliary liquid should be water and the water temperature should be kept at 20℃.
