1Introduction
Simple and compact
The METTLER TOLEDO DM40/DM45 DeltaRange/DM50 Density Meters are modern, compact instruments suit
able for use in a vast diversity of application areas. They can be used, for example, in quality control as well as
in research and development and meet the most demanding requirements.
These compact density meters perfectly combine simple, easy-to-understand operation with a high level of
measuring accuracy and outstanding reliability. With their plug & play capability, they automatically detect
external devices and sensors.
The density meters can be operated as standalone instruments or run from a computer using the LabX PC soft
ware. Straightforward user guidance on the large color touchscreen enables intuitive operation. User-definable
shortcuts allow all functions to be activated directly from the home screen with a single click.
Touchscreen control of the instrument and the method function parameters are described in the Operating
Instructions. The Installation Instructions explain all the necessary steps for setting up your instrument. You are
then guided through the first density measuring process with the aid of a practical example.
If you have any additional questions, METTLER TOLEDO is always available to assist you.

2Safety measures
These instruments have been tested for the applications documented in the appropriate operating instructions.
However, that does not absolve you of the responsibility to check for yourself the suitability of the products sup
plied by us for the procedures and purposes for which you intend to use them. You should therefore observe the
following safety measures.
Measures for your personal protection
Risk of electric
shock
Risk of explosion
Risk of corrosion
●
Ensure that you plug the supplied power cable into a socket that is grounded! In the
absence of grounding, a technical fault could be lethal.
●
Only use the power supply which was supplied with the device.
●
Never work in an environment subject to explosion hazards! The housing of the
instrument is not gas tight (explosion hazard due to spark formation, corrosion
caused by the ingress of gases).
●
Test highly combustible, poisonous or corrosive substances under an extractor
hood and follow the normal laboratory rules and precautions.
●
When using chemicals and solvents, comply with the manufacturer's instructions
and the general lab safety rules!
Measures for operating safety
●
Do not clean the measuring cell with conc. caustic soda (sodium hydroxide, NaOH)
or hydrofluoric acid (HF)! Both substances will chemically corrode the measuring
cell.
●
Caution
Exclude the following environmental influences:
- Direct sunlight
- Air humidity above 80%
- Ambient temperatures below 5 °C and above 35 °C
- Powerful electrical or magnetic fields capable of affecting the power supply due to
large load changes
- Strong vibrations
Only have the instrument serviced by an authorized METTLER TOLEDO Service agent!
