Density measurement: New technology for an unbeatable price

2018-02-05 | Corporate

In continuous communication with customers worldwide, technology and features have been updated to build a generation of density meters that operates on a new level. The new DMA™ 501 proves to be a worthy successor of the widely acknowledged DMA™ 500 density meter. It is accompanied by the launch of the 4-digit-accuracy density and concentration meter DMA™ 1001; the most powerful density meter in its price range.

The newly designed oscillating U-tube and a patented new measuring principle of the oscillation period are integrated in both instruments. DMA™ 1001 is particularly special: It is the first benchtop density meter entirely tailored to meet the lab standards required by industry – at a reasonable price. “Compliance with standards is gaining more and more importance in a wide range of industries. That is why we created a density meter with 4-digit accuracy that meets this demand and is still affordable for many,” says product manager Julia Sattler. “In the density meter market, DMA™ 1001 has an unprecedented price-performance ratio.”

Both instruments, DMA™ 501 and DMA™ 1001, are available now. They are prepared to handle a huge variety of samples, including those with challenging characteristics: The new syringe holder and the viscosity correction over the full measuring range ensure highly accurate results that are independent of external influences. In addition, users will feel even more at home with the brand new user interface. It comes with the look and feel of a smartphone operating system and on a bright 7’’ touchscreen.

New technology for all Anton Paar density, sound velocity, and viscosity instruments

In the wake of updating the technology for digital density measurement, Anton Paar has already relaunched several instrument series that feature the new patented oscillation period measurement over the past year. This includes further density meters, benchtop and portable, as well as sound velocity meters, viscosity meters, sample changers, and the entire portfolio of process sensors that perform density measurements. All new instruments come with a range of new or upgraded technology and features. The highlights of the instruments are:
