4 DMA 35 - an Overview
The portable density meter DMA 35 measures the density of liquids in g/cm
3
or kg/m
3
according to the oscillating U-tube principle. Apart from density you can select various
further measuring units (relative density, density at reference temperature,
concentrations). A temperature sensor measures the sample temperature right at the
measuring cell. The temperature is displayed and can be used internally for automatic
temperature compensation of the density reading if required.
Owing to the lightweight and compact design one can easily perform measurements
of usually difficult accessible samples. The backlight of the display ensures clear
visibility of results, even in dark surroundings. The backlight of the oscillator at the
same time enables to observe the filling process in detail.
Samples are filled into the measuring cell using the built-in pipette-style pump or a
syringe. You can allocate sample IDs to your samples for easier identification. You can
also define and store different measuring methods allowing acceleration of repeatedly
performed standard measurements.
DMA 35 is operated via seven keys. 1024 measuring data including date, time and
sample ID can be stored in the memory of the DMA 35 density meter and can be
recalled, exported to a PC or printed later. The transfer of the stored measuring data
to a printer or PC is done wireless using an infrared interface (IrDA).
The product version DMA 35 Tag&Log is additionally equipped with an RFID
interface. Via this interface, sample IDs and/or methods can be uniquely linked to an
RFID tag. Later on, by reading the RFID tag, you can switch fast and easily between
different sample IDs and methods which further increases the efficiency of your
measuring process.
The intrinsically safe product versions DMA 35 Ex and DMA 35 Ex Petrol (ATEX
marking
II 2 G Ex ib IIC T4) are suitable for use within potentially explosive areas.
The DMA 35 Ex is ideal for chemical applications and measuring battery acid. The
DMA 35 Ex Petrol comes with a special housing for petrochemical applications,
resistant to petrols and similar solvents.
The product versions DMA 35 Ex and DMA 35 Ex Petrol are also equipped with an
RFID interface.
