Meter Density DMA 35


add to cart

The DMA™ 35 portable density meter measures the density and concentration of your sample and is characterized by the highest level of user-friendliness. It employs the oscillating U-tube principle from Anton Paar. This means: 50 years of density measurement experience in one small instrument. The robust and lightweight design of DMA™ 35 enables on-site operation in a wide range of work environments. Two milliliters of sample are taken directly from the storage container and measured within seconds – without the need to transport the sample to the lab. Due to its flexibility, DMA™ 35 can also be used as a mini-benchtop instrument.
