How to Choose A Density Meter for your Application.
Selecting a Density Meter model for chemical, pharmaceutical, petroleum, cosmetics, essential oils, petro-chemical, education, and university applications. The Rudolph DDM2910 and DDM2911 offer a wide range of sample handling, sample loading, method management, measurement, and measurement fail-safe options. Rudolph Density Meters address each aspect of the the density measurement process to ease and speed sample handling, manage measurement methods, monitor the density meter’s testing environment, and aid the operator with clear controls and a crisp digital display. The Rudolph Advantage in Density Meters includes:
Density Meters with On-board Flexible Method Management
Factory installed density meter measurement methods allow for immediate selection of the correct method to match the most common applications.
For unique density measurement applications, create a sample method using an unlimited number of Concentration Tables, Formulas, and Polynomials to match the density measurement methods used in your laboratory.
Setting up your custom method on your Density Meter is as simple as filling out a few screens.
Density Meters with Wider Measurement Range:
The Rudolph DDM2910 and DDM2911 Density Meters can measure samples from 0 degree C to 90 degree C offer temperature control to one of the widest in the industry giving you the correct temperature for your measurement application.
Density Meters from Rudolph Research offer VideoView™ Bubble Detection
No more straining to see small difficult-to-detect air bubbles in your sample with live on-screen video viewing. On-screen bubble detection is made possible utilizing Rudolph’s exclusive, patented VideoView™ with 10X magnification. No other instrument manufacturer offers this technology or helps the instrument avoid error causing air bubbles like Rudolph Research.

Rudolph Research offers Density Meters with 21CFR Part 11 Instrument Level Compliance
Oscillating U-Tube with Viscosity Correction and Reference Oscillator
The Rudolph Research Density Meter’s oscillating U-tube with full range viscosity correction and reference oscillator (patent pending) allows long term calibration stability and measurement at all temperatures with a single calibration.
- Calibrate the DDM2910 and DDM2911 with 2 or 3 Traceable Standards – calibrating with merely air and water appears inconsistent with cGMP/GLP compliance regulations. (see H&D Fitzgerald’s recommendations at www.density.co.uk )
- Can print out complete method configuration, communication settings, as well as calibration verification and calibration adjustment data/history.
- Measured values can be shown continuously as temperature stability is being reached or, at the discretion of the user, measured values will only be displayed once the final answer is reached and completely stable.
- Unlimited number of customized calibration adjustments and calibration verifications possible.
Computer Windows Based Flexibility
- 8 gigabytes of internal memory allow almost unlimited capacity for saving measurement data. The DDM 2911 and DDM 2910 Density Meters are network ready and data may also be saved directly to your server or to any directory desired.
- Internet access is possible directly from the DDM2910 or DDM2911 touch screen.
- Disk Protection feature protects the operating system against malware infections in networked environments.
- Windows based navigation architecture is so intuitive that most operators will never read the manual. But should you wish to reference the manual, it is stored right on the DDM 2911 and DDM 2910′s internal memory
- Copy methods, transfer concentration tables, download data, etc., via one of the 2 of 5 total USB ports on front of unit.
- Three additional rear USB ports allow for quick and easy connection to a mouse, keyboard, printer, bar code scanner, or memory stick.
Versatile Communication Capability
- Cat 5 Network Cable Connection
- 5 USB ports
- 2 RS 232 Ports
Traceable Calibration Standards
Rudolph knows how important it is to calibrate with Traceable Standards and therefore, we include either a NIST or UKAS standard in the accessories provided with both our DDM2910 and DDM2911 Density Meters.
Density Meters easily integrate with Laboratory Automation Flexibility
Rudolph Research knows you need to save time and thus money performing routine measurement tasks. Using a Rudolph Density Meter as the heart of the system we can combine multiple instruments to produce measurement routines on up to 240 sample. We can design a custom configuration just for your application.
With decades of worldwide laboratory instrument design and sale Rudolph Research knows you application requirements and can help you select the right instrument including the right Density Meter from our innovative line of products.
