Density measurement redefined

Thanks to Anton Paar's latest innovation - the patented Pulsed Excitation Method (PEM) - the company's digital density meters have set new benchmarks in terms of repeatability and reproducibility. The top of the line and unrivaled DMA 5000 M is the most precise digital density meter you can get.

With its six-digit accuracy, DMA 5000 M is the most precise digital density meter on the market. The patented Pulsed Excitation Method delivers the most stable density results based on comprehensive knowledge of the oscillation characteristics. The influence of viscosity is compensated twice as effectively as ever before. It is ideal for your high-end R&D applications and sets the tone at authorities as well as standards organisations.The unique design of the measuring cell, a novel way of evaluating the oscillation characteristics, and many other innovative features lead to the following:

The most excellent repeatability and reproducibility

The new patented Pulsed Excitation Method (PEM) gains three times more information from the U-Tube’s oscillation characteristics compared to conventional methods. This allows Anton Paar to guarantee unparalleled repeatability and reproducibility for most accurate density values across the entire temperature range.

Leading viscosity correction

Thanks to PEM the influence of viscosity is compensated twice as effectively as ever before across the entire viscosity range of samples. Even for Newtonian fluids, PEM delivers the viscosity in addition to the density value with an accuracy of 5 % in the range from 10 mPa·s to 3,000 mPa·s.

Maximum ease of use

The U-View™ camera feature displays and stores pin-sharp images of the entire oscillating U-tube sensor and the filled-in sample, so you have the details at hand at any time. The combination of U-View™ and the automatic real-time bubble detection function – FillingCheck™ – monitors the entire measurement sequence and allows later verification of the results, which is particularly useful when using automatic sampling systems.

ThermoBalance™ temperature management

The DMA M series provides stable readings over extended periods of time. After just one adjustment at 20°C. You can change sampling temperatures quickly between 0°C and 100°C whenever needed and rely on immediate temperature stability.
