DMA 1001 and DMA 501 are compact and stand-alone density meters that easily fit into tight spaces in your production area, storage facilities, or in the lab, enabling you to perform quick quality checks just around the corner. Even if the sample characteristics are challenging, the newly designed oscillating U-tube which works according to the patented Pulsed Excitation Method delivers the most stable density results based on comprehensive knowledge of the oscillation characteristics. Lab chemists, production employees as well as summer interns will be familiar with the easy-to-learn working routines from the start. 

Key features

A revolutionary measuring principle

The new design of the measuring cell and a novel way of evaluating the oscillation characteristics lead to stable results, more independent from external factors than ever before.

100 % uptime: Rugged design meets intelligent condition monitoring

100 % uptime: Rugged design meets intelligent condition monitoring

  • Intelligent condition monitoring system which gives a warning and recommended action if environmental conditions are not in the ideal range
  • Reliable density measurement also on creams, emulsions, paints and varnishes, scouring agents, and even aerosol sprays
  • Optional peristaltic pump for automated filling of low-viscosity samples
  • Integrated conversion tables for simple density and concentration measurement (no manual calculations necessary)
Accurate and traceable density results unaffected by external factors

Accurate and traceable density results unaffected by external factors

  • U-View™ and FillingCheck™: the pin-sharp camera and automatic filling error detection keep records about proper sample filling for subsequent transparency, no matter who performed the measurement.
  • Standardized sample handling: the syringe holder eliminates the potential influences from different users, syringe types, or syringe filling volumes
  • Potential errors due to the viscosity of samples are automatically corrected over the full range
  • Optional ISO 17025 calibration certificate, with guaranteed traceability to SI units
Worry-free operation, also outside the traditional lab space

Worry-free operation, also outside the traditional lab space

  • Robust lab density meter with flexible installation site, suitable also for production environments or storage areas
  • Storage of 5000 results including timestamp, sample name, camera images, and potential filling warnings for later verification of stored results
  • Print your customized result reports or export them to a PC via USB, Ethernet, or RS232
  • Brand-new customizable user interface with the look and feel of a smartphone, operated via a 7” touchscreen
  • All results visible at a glance or one value in big font – the screen layout is up to you
  • Customizable home screen with quick access to favorite functions
  • Connect a keyboard, mouse, or bar code reader for convenient instrument operation and entry of sample names
