21CFR Part 11 compliant density meters with a wide measurement range and on-screen bubble detection

Density Meters

  • On-screen bubble detection
  • Wide measurement range
  • 21CFR Part 11 compliant

Ideal for both research and production applications across many industries including chemical, petroleum, pharmaceutical, petro-chemical and beverage, our density meters are available in a variety of specifications.

All Rudolph Research Analytical density meters have on-screen bubble detection a magnified view of the entire U-tube. The VideoView feature provides superior high resolution visual bubble detection of your sample with live on-screen video viewing. Images can be saved with the sample results and may be viewed and printed. A full view of the entire U-tube is possible at 2X magnification. The U-tube can zoom to 6X or 10X to ensure it is air bubble free. The 6X and 10X magnification are also extremely helpful in detecting the cleanliness of the U-tube.

Other features include flexible method management, sample handling and loading options, various measurement ranges, and measurement fail-safe. The DDM2910 and DDM2911 density meters can measure samples from 0 to 90 degrees C, offering one of the widest temperature control ranges in the industry.
