Why truth feels better: New DMA Generation M density meters

Density and concentration meters have been a point of pride at Anton Paar ever since the company produced the world''s first digital density meter in 1967. Decades of development later, Anton Paar now offers the world''s most accurate density meter, DMA 5000 M. Building on this, the focus in developing the latest DMA Generation M models was on offering users even more convenience and safe operation. The following benefits are unique to DMA 4100 M, DMA 4500 M and DMA 5000 M.

PCAP touchscreen

The 10.4” touchscreen employs projected capacitive technology (PCT/PCAP) for a state-of-the-art user experience. Operation is easy, even when wearing gloves. One main screen tells users what they need to know even from a distance, thanks to adaptable font sizes.

FillingCheck™

DMA Generation M density meters automatically detect filling errors or bubbles in the sample in real time, alert users and document the incident. Correct sample filling is ensured, regardless of the conditions.

U-View™

Users can check their sample filling process via a high-quality image of the whole measuring cell on the instruments'' screen or recall stored images of the entire filled-in sample at any later time. The stored images allow users to later verify correct sample filling and measurements, particularly when using automatic sampling systems.

ThermoBalance™

ThermoBalance™ eliminates the need for multi-temperature calibrations and allows for quick and accurate measurements at very different temperatures. Owing to the systems'' compact mechanical setup, drifts due to temperature stress are compensated even when samples are filled at temperatures very different from the measuring temperature. Stable readings are provided over extended periods of time.

Viscosity correction

The sample''s viscosity causes damping of the oscillating U-Tube, which would normally reduce the achievable repeatability and accuracy of the measurement. To avoid this effect, DMA Generation M meters automatically correct the viscosity influence on the measured density over the full range of densities, viscosities and temperatures. Systematic errors due to the sample''s nature are eliminated.
