The Rudolph DDM 2911 PLUS, Automatic Density Meter is our most capable instrument offering our widest measurement range, highest accuracy, and the on-board range methods and electronic data tracking required in the most demanding laboratories in the world. The DDM 2911 PLUS is highly recommended for high level work in the Pharmaceutical, Chemical, and Petroleum industries. With 0.00001 g/cm3 accuracy the DDM 2911 PLUS is an excellent choice for the Alcohol Beverage industry to measure alcohol concentration to determine alcohol Proof.
Designed for the most demanding cGLP/GMP Laboratories the DDM 2911 PLUS Density Meter offers density accuracy to 0.00001 g/cm3, Resolution: Density 0.000001 g/cm³, and Temperature Selectable to: 0.001°C
VideoView provides superior high resolution visual bubble detection within your sample with live on-screen video viewing. Simultaneous images of both a 2X magnification view of the entire U-tube and a 10X magnification, with a scanning video is possible. 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.
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:
(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.
The DDM 2911 PLUS’s standard communication package includes:
Sample measurement reports are edited quickly and easily. Just import your logo to the DDM 2011 PLUS Density Meter and print your company’s customized “C of A” directly.
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 all of our density meters. The DDM 2911 PLUS standard accessories include:
The Rudolph DDM 2911 PLUS Density Meter can be combined with various automation products to speed your sample measurements.
The Rudolph Research R837 AutoFlex is a perfect instrument combination for labs where a high
volume of daily samples are required.
