Densímetro portátil: DMA™ 35

For quick density and concentration measurements on-site, directly at the sample storage container.

The DMA™ 35 portable density meter measures the density and concentration of your sample in a few seconds directly on-site and uses only two milliliters of sample. Sample names are identified via the RFID interface and stored together with the result shown on a big color display Data exports or printouts are done wirelessly via Bluetooth®.

DMA™ 35 is prepared for field use in harsh environments. If the measuring cell nevertheless suffers from cell rupture, you benefit from the patented connection of the measuring cell, which allows replacement.

Operation of DMA™ 35 is easy for right- and left-handed users. The capacitive keys help you to navigate through the menu. For filling viscous samples, DMA™ 35 can also be used as a mini benchtop instrument. The new pump can be locked to prevent sample carryover and due to the automatically rotating screen results are easy to read at any instrument position.

Características clave

From hydrometers to portable digital density meters: Density measurement has certainly experienced an evolution. While there are different methods still in use today, digital density measurement has many advantages compared to older methods such as measuring density with hydrometers.

Reasons to go digital

  • Measurement directly at the sample container
  • Requires only 2 mL of sample, filled via the built-in pump
  • Preinstalled and programmable concentration units and product-specific parameters – no further calculations are necessary
  • Each unit covers the whole relevant measuring range
  • Results available in seconds
  • Perfect traceability of results

Unbeaten usability – for fast measuring routines 

  • Intuitive user interface
  • Operated via capacitive keys with a sensitivity suitable for use with or without gloves
  • Suitable for both left- and right-handed users
  • High-resolution color display 
  • Measuring cell with inspection window and backlight 
  • No-hassle measurement of hard-to-reach samples 

Robust design – for a long working life

  • Leakproof sealed housing for industrial and field applications (protection class IPX4)
  • Additional rubber protection of the measuring cell
  • Robust hard-glass front
  • Smart oscillator connection enables replacement in case of cell rupture

 Perfect traceability – for comprehensive data control

  • Storage of up to 250 sample IDs for easy sample identification
  • RFID interface for changing measurement settings quickly by reading RFID tags
  • Storage of up to 30 measuring methods
  • Storage of up to 1024 measurement results including time stamp and sample ID
  • Bluetooth® interface for data exchange with a PC and data export to a printer

One instrument – for a huge variety of samples

  • Stable tabletop position for syringe filling (recommended for viscous or expensive samples)
  • Lock-position of pump reduces dead space when filling with syringe
  • When the instrument is filled from the top, the display rotates automatically.
  • Influence of viscosity on your density result is automatically corrected
