Take DMA 35 with you at all times and measure the density and concentration of your sample directly on-site. One portable density meter replaces all the glass hydrometers in your workplace and gives you the accuracy expected from a lab instrument. DMA 35 uses only two milliliters of sample and saves you a lot of time as there is no need to transport the sample to the lab. It is built to withstand the knocks and spills of outdoor use. An RFID interface for quick sample identification and a Bluetooth® interface for convenient data handling in the field are integral parts of the instrument.

All products are delivered with factory calibration.

Key features

A portable density meter providing accurate results, also under harsh conditions

The splash-proof DMA 35 is made for density and concentration measurement in harsh environments, including outdoor operation, while providing the accuracy expected from a lab instrument. The smart oscillator placement makes sure that gas bubbles move to where they can’t affect your result: outside the measuring cell.

Designed for on-site density measurements

Designed for on-site density measurements

  • Leak-proof sealed housing to withstand harsh conditions in industrial and field applications
  • Additional rubber protection keeps the measuring cell safe
  • Operation via capacitive keys so sensitive they can be used with gloves
  • Suitable for both left- and right-handed users
  • RFID tag readings, measurement start or abort, via gesture control: One hand is free to hold you steady with hard-to-reach samples.
  • For sample temperatures up to 100 °C, quick decision support, e. g. in the beer brewing process (measurement of hot wort)
  • Graphical visualization of the fermentation process for each fermentation tank
  • Smart patented oscillator connection (AT516421 B1, EP3015847 B1) permits replacement in case of cell rupture
Intrinsically safe – for use in hazardous locations

Intrinsically safe – for use in hazardous locations

  • Intrinsically safe models DMA 35 Ex and DMA 35 Ex Petrol (Ex marking [Ex] II 2 G Ex ib IIB T4) for use in hazardous areas
  • The only option available on the market for safe measurements in explosive atmospheres
  • DMA 35 Ex is particularly suitable for measuring flammable chemicals.
  • DMA 35 Ex Petrol provides excellent resistance to petroleum samples and fully complies with the ASTM D7777 and IP 559 standards.
Fastest filling and measurement – for a huge variety of samples

Fastest filling and measurement – for a huge variety of samples

  • Fill all kinds of samples – no matter what the viscosity is – in one second using the built-in manual pump or a syringe.
  • No expensive electrical wearing parts: You can easily do all cleaning and maintenance work yourself.
  • Measuring cell with inspection window and backlight for convenient inspection of proper sample filling
  • The most reliable portable density meter for fermenting beer or wine, due to intelligent oscillator placement (potential bubbles automatically move outside the measuring cell)
  • Lock-position of pump preventing sample carryover
  • Auto-rotating display for perfect visibility of results at any instrument position
  • Influence of viscosity on your density result is automatically corrected: for reliable measurements, also on highly viscous samples
Perfect traceability of density and concentration results

Perfect traceability of density and concentration results

  • 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 1024 measurement results including time stamp and sample ID
  • Wireless data exchange with a PC (csv or txt format) and data export to a printer via Bluetooth® for convenient data handling in the field – no extra software required
Leave your glass hydrometer or pycnometer for a digital density meter

Leave your glass hydrometer or pycnometer for a digital density meter

  • Measurement directly at the sample container
  • Requires only 2 mL of sample, filled via the built-in pump
  • Preinstalled and programmable concentration units – no further calculations necessary
  • Results available in seconds
  • Perfect traceability of results
