Density meter: DMA™ 4500 M
Follow your instincts: best-in-class 5-digit density meter that will get the job done.
For thousands of users around the world, density measurement means DMA™ 4500 M. These density meters are in use day in, day out, wherever reliable and accurate 5-digit density values are required.
To achieve this, the patented Pulsed Excitation Method applied by DMA™ 4500 M delivers the most stable density results based on comprehensive knowledge of the oscillation characteristics. This method results in viscosity correction which is twice as effective as anything else available on the market. The automatic bubble detection system gives you back control of your filling. With this unique method you also benefit from built-in intelligence: frequently changing users with differing filling approaches, humidity, air pressure, and instrument condition, all these have no effect on the operation and results.

A revolutionary measuring principle for the density meter which leads the way
The unique design of the measuring cell, a novel way of evaluating the oscillation characteristics, and many other innovative features lead to the following:

Supervise your filling quality and be alerted if there is an error
- The U-View™ camera feature displays and stores live images of the oscillating U-tube sensor and the entire filled-in sample
- Relevant images with the sample fully and clearly visible are stored in the data memory
- Later review of these images guarantees completely transparent measurement processes
- U-View™ and FillingCheck™, the automatic real-time bubble detection feature, supervise the entire measurement sequence and allow later verification of the results, which is particularly useful when using automatic sampling systems

Touchscreen for premium user experience
- The only density meter with PCAP touchscreen technology for unmatched sensitivity and robustness at the same time
- Easy operation, even when wearing gloves
- Large screen, readable from a distance due to adaptable font sizes

ThermoBalance™ temperature management
- No temperature-related fluctuations
- No temperature-related aging effects on the measuring cell
- Change between temperatures quickly without drifts and rely on immediate temperature stability

Leading viscosity correction
- Automatic viscosity correction across the entire viscosity range of samples
- Eliminates viscosity-related errors twice as effectively as ever before
- No viscosity standards required

Fit for pharmaceutical demands
- Full QM, GMP/GLP, and 21 CFR Part 11 compliance
- Audit Trail
- Password protection with three user levels and customizable user group administration to prevent accidental changes
- Forgery-proof data export
- Different security levels and increased security settings
- Electronic signature
