Portable Density Meter: DMA 35

Overview

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.

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

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
