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

• 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 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

• 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

• 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

• 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

Quickly determining the state of charge of lead-acid batteries

• Determination of the specific gravity of sulfuric acid
• Used for measurement of sulfuric acid in lead-acid battery production and maintenance of uninterruptible power supply (UPS) systems
• Protection class IP54 and high chemical resistance
