1 Introduction
Thank you for buying the DMA 4100, DMA 4500 or DMA 5000 density/specific
gravity/concentration meter for gases and liquids. We greatly appreciate your
trust and will do everything we can to ensure that your instrument provides you
with years of trouble-free operation.
This instruction manual includes a CD-ROM with further information on the
DMA 4100/4500/5000. If the autostart function of your PC is deactivated, start the
CD by double-clicking the file "index.html" in the CD folder. If required, you can
install browser software and Adobe Reader from the folder "software" on the CD.
The DMA is the first oscillating U-tube density meter which measures with the
highest accuracy in wide viscosity and temperature ranges.
A unique reference oscillator, in addition to the U-tube oscillator, provides
extraordinary long-term stability and makes adjustments at temperatures other
than 20 °C virtually unnecessary.
By measuring the damping of the U-tube's oscillation caused by the viscosity of
the filled-in sample, the DMA automatically corrects viscosity-related errors.
Two integrated Pt 100 platinum thermometers provide the highest accuracy of
temperature control. These are traceable to national standards.
To perform a measurement, select one out of a total of 10 individual measuring
methods and fill the sample into the measuring cell. An acoustic signal will inform
you when the measurement is finished. Results are automatically converted
(including temperature compensation where necessary) into concentration,
specific gravity or other density-related units using the built-in conversion tables
and functions.
The density results, including sample number or name, can be shown on the
programmable LC display, printed out or transferred to the data memory.
For fully automatic measurements, the DMA can be connected to an automatic
sample changer or sample handling units.
Some software features, like temperature scan and adjustment at high density or
viscosity, are only available with the DMA 5000.
