DMA 35 Portable Density and Concentration Meter

DMA 35 is your portable digital meter for determining density, specific gravity, and concentration directly at the sampling location. It is prepared to withstand the knocks and spills of outdoor use. 

DMA 35 Ex and DMA 35 Ex Petrol for use in hazardous areas are the only intrinsically safe portable density meters on the market and are certified according to the latest ATEX and IECEx standards. 

DMA 35 Ampere is the ideal solution for measuring the specific gravity of sulfuric acid in lead acid batteries.

Anton Paar is the pioneer and market leader in the field of density and concentration measurement. Our renowned DMA density meters based on the oscillating U-tube principle have been advanced over decades in direct response to customers' needs.

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.
