Setting up your custom method on your Density Meter is as simple as filling out a few screens like the one below:
Rudolph Density Meters offer VideoView™ Bubble Detection
VideoView provides superior high resolution visual bubble detection within your sample with live on-screen video viewing. The U-Tube may be viewed at 2X, 6X and 10X magnification, for the entire U-tube. The 10X magnification is also extremely helpful in detecting the cleanliness of the glass U-tube. Both images may be saved with sample results and may be viewed and or printed as desired.
A full view of the entire U-tube is possible without any obstruction. Automatic Scanning of U-tube under the 10X magnification of the entire U-tube and manual control is possible to view any position of the U-tube for bubble detection. The clarity, magnification and resolution is the very best available. Rudolph’s exclusive VideoView is protected under Patent #7,437,909.
- 2X, 6X and 10X magnification U-tube is possible.
- The entire view of the U-tube is available for both images.
- Both images are saved and can be viewed, exported and/or printed with measurement results.
- Automatic Bubble detection is available which will flag the sample(s) with suspected bubble.
Computer Windows Embedded Based Flexibility
- 32 gigabytes of internal memory allow almost unlimited capacity for saving measurement data. The DDM 2911 PLUS is network ready and data may also be saved directly to your server or to any directory desired.
- Internet access is possible directly from the DDM 2911 PLUS touch screen. The 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 PLUS internal memory.
- Copy methods, transfer concentration tables, download data, etc., via the USB ports on the front of unit.
- Five USB ports allow for quick and easy connection to a mouse, keyboard, printer, bar code scanner, or memory stick.
- Embedded Windows 7 prevents any and all viruses and malware.
The Rudolph 2911 PLUS Density Meter offers 21CFR Part 11 Instrument Level Compliance
The DDM 2911 PLUS’s 21CFR Part 11 software module is easily enabled through the user friendly touch screen. This module gives you full compliance with:
- Electronic Signature

Oscillating U-Tube with Viscosity Correction and Reference Oscillator
(patent # 7,735,353)
The DDM 2911 PLUS oscillating U-tube with full range viscosity correction and reference oscillator allows long term calibration stability
and measurement at all temperatures with a single calibration.
- Calibrate the DDM 2911 PLUS with 2 or 3 NIST Traceable Standards – calibrating with merely air and water appears inconsistent with cGMP/GLP compliance regulations.
- 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.
- Complete History of Calibration Adjustments and Verifications are available to View, Print, and/or Export.
- Possible to set calendar reminders as to when Calibrations are due.
