DMA™ 35 Portable Density Meter

On-site density and concentration measurements in just a few seconds

Take DMA™ 35 with you at all times and measure the density and concentration of your sample directly on-site. The portable density meter uses only two milliliters of sample. In addition, it saves you a lot of time as there is no need to transport the sample to the lab. DMA™ 35 is built to withstand the knocks and spills of outdoor use. If the measuring cell nevertheless suffers from cell rupture, you benefit from the unique patented connection of the measuring cell, which allows replacement. To top it all off, DMA™ 35 can also be used as a mini benchtop instrument: Turn it upside down, put it on a table and fill the sample with a syringe.

Key Features

A portable digital density meter provides significant benefits for quality control

From hydrometers to portable digital density meters: Density measurement has certainly experienced an evolution. Compared to measuring density using older methods, digital density measurement employing the oscillating U-tube principle from Anton Paar has many advantages.
