DMA 35 Basic is the entry-level handheld density meter that takes samples directly from the storage container with the help of the built-in pump and measures them on-site. Results are given as density or concentration, for example in °Brix, %v/v alcohol, or %w/w H2SO4. Because of its lightweight and flat design, hard-to-reach samples, such as automotive batteries stored on narrow racks or wine samples out of stacked wine barrels, can be conveniently measured.

Key features

The benefits of a handheld density meter over a glass hydrometer

The benefits of a handheld density meter over a glass hydrometer

  • No waste of sample: only 2 mL required
  • Sample is taken directly from the container using the built-in pump
  • Integrated conversion tables: results are shown in the preferred unit without the need for further calculations
  • Wide measuring range: one digital instrument replaces a whole set of hydrometers
  • Automatic temperature compensation: results available in seconds
  • Storage of data and easy data transfer: no chance for errors when writing down results manually
  • User-independent results
