10 The “Density” application
In this section you will be introduced to the “Density” application. You will find practical information about working with this applica-
tion and about the different settings. Please note that all settings for the “Density” application are saved under the active user
profile, so each user can make their own settings for this application. Because of this, first make sure that you have selected
the desired user profile.
10.1 Introduction to the “Density” application
The “Density” application enables you to determine the density of solid bodies, liquids, and pasty substances. Every sample can be given
an identification, and the built-in statistics functions allow statistical evaluation of measurement series. Determination of the density
uses Archimedes' principle according to which a body immersed in a fluid undergoes an apparent loss in weight which is equal to the
weight of the fluid it displaces.
To perform density determinations you can use the hanger for weighing below the balance which belongs to your balance. Note:
Balances with the M weighing platforms XP16001M and XP20001M, as well as all balances with the L weighing platform require the
hook 11132565 from the accessories line (see Operating Instructions – Part 1). However, to determine the density of solid bodies, we
recommend you to work with the optional density kit which contains all the attachments and aids needed for convenient and precise
density determination. The density kit is supplied with separate instructions which explain how to install and use it.
To determine the density of liquids, you additionally need a sinker which you can also obtain from your METTLER TOLEDO dealer.
Alternatively, the “Density” application also supports the use of a pycnometer for determining the density of liquids. Pycnometers can
be obtained from companies specializing in laboratory equipment. To determine the density of pasty substances a gamma sphere is
required; your dealer will be pleased to tell you where this can be obtained.
Please take note of the instructions which are supplied with these accessories; they contain useful information about working with the
aids as well as for their handling and care.
10.2 Selecting the Application
If the “Density” application is not already active, press the «D» key. In the selection window,
touch the symbol of the application.
When you have selected the application, the display shown at left appears. Special func-
tion keys and information fields for density determination are activated at the factory. The
balance is preset to use water as the auxiliary liquid for density determination. However,
you can change these settings according to your needs as described in the sections that
now follow.
