E15IB001EN-N 7
2 DMA 501 / DMA 1001 – An Overview
The compact DMA 501 / DMA 1001 density meter
measures the density of liquid samples by use of the
oscillating U-tube method that has been first intro-
duced on the market by Anton Paar in 1967. It
combines high precision with easy operation and
robust design. The instrument will cope with almost
any sample that you can fill and clean.
Accurate results in the shape required
The instrument corrects viscosity-related errors
automatically. An integrated Pt 100 platinum ther-
mometer together with Peltier elements provide an
extremely precise thermostatting of the sample.
The density value can be automatically converted
into concentration values for numerous generic user
products (already factory-programmed).
Precise sample filling
Accurate and repeatable results strongly depend on
bubble-free filling ensured by the peristaltic pump
optionally integrated in the instrument.
FillingCheck™ automatically detects gas bubbles in
the measuring cell by an advanced analysis of its
oscillation pattern, and will generate a warning
message in that case. Additionally you can visually
inspect the measuring cell on the real-time camera
image (U-View™).
Intuitive user interface
Operate the instrument via the touchscreen user
interface giving you the look and feel of a smart-
phone. If you prefer, you can optionally connect an
external keyboard or mouse and a barcode reader.
Data export/printouts
You can export all measured data as a PDF or CSV
file onto any connected storage device. Data can be
printed via USB, network, or serial port.
2.1 Intended Use of the Instrument
DMA 501 / DMA 1001 is capable of measuring
nearly every liquid, independent of its composition
and viscosity.
Typical samples include soft drinks, various types of
oil, acids and bases, infusion solutions, pastes and
creams from applications as diverse as petrochem-
icals, food & beverages, chemicals, pharmaceuti-
cals and cosmetics.
Restrictions
Do not leave bases longer than necessary in the
measuring cell, because the glass of the measuring
cell is susceptible to attack by alkaline liquids.
Exclusions
• The instrument cannot measure solids.
• Do not measure hydrofluoric acid as it attacks
the glass of the measuring cell.
• Do not fill substances that may harden inside
the measuring cell.
• Do not mix substances inside the measuring
cell if these substances may react chemically.
• Do not use mechanical action for cleaning the
measuring cell.
IMPORTANT: Always check if recommendations of
the instrument (e.g. from the instrument’s intelligent
condition monitoring) are reasonable.

3 Installing the Instrument
3.1 Installation Requirements
To achieve best measurement results, operate the
instrument under typical laboratory conditions:
- 23 ±2 °C (73.4 ±3.6 °F) ambient temperature,
- < 60 % relative humidity,
- no direct sunlight.
The setup location and surroundings must meet the
minimum requirements specified under “Operating
conditions” in the technical data (appendix A.2).
Also observe the safety instructions in section 1.
Allow the equipment to reach ambient temperature
before installation. This is particularly important if
the equipment has been stored or transported at
lower temperatures.
IMPORTANT: High humidity or a measuring tem-
perature that is significantly below the ambient tem-
peraturemayleadtocondensationinthemeasuring
cell. In this case take measures to avoid condensa-
tion as described in the reference guide.
The right place
Place the instrument on a stable, flat desk that is free
of vibrations and away from vibrating equipment.
To ensure temperature stability and trouble-free
measurement, do not position your instrument:
- next to a heating facility,
- in a drafty place (e.g. near an air conditioning,
ventilation system, or an open window),
- in direct sunlight.
Leave enough room (approx. 10 cm/4 in) between
the cooling fins on the rear of the instrument and any
wall. Also ensure that the heat can freely dissipate.
Do not install the instrument in a cabinet.
The instrument requires an electrical outlet nearby:
- AC 100–240 V, 47–63 Hz, 1.5 A
