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 Laboratory Density Meter 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. Just a few of the many possible customized sample methods shown below:
Setting up your custom method on your Density Meter is as simple as filling out a few screens like the one below:
Density Meters from Rudolph Research offer a full view of the U-Tube for effective Bubble Detection
No more straining to see small difficult-to-detect air bubbles in your sample with live on-screen viewing of the entire U-Tube. On-screen bubble detection is made possible utilizing Rudolph’s exclusive camera that allows a 2X, 6X and 10X magnified view of the entire U-Tube. No other instrument manufacturer offers this technology or helps the user avoid error causing air bubbles like Rudolph Research.
The Rudolph 2911 Density Meter offers 21CFR Part 11 Instrument Level Compliance
The perfect pharmaceutical density meter, the DDM 2911’s 21CFR Part 11 software module is easily enabled through the user friendly touch screen. This module gives you full compliance with:
Electronic Signature
Access Levels
Internal write protected storage
Unique passwords
Write protected documents sent directly to server
Oscillating U-Tube with Viscosity Correction and Reference Oscillator
(patent # 7,735,353)
The DDM 2911 Density Meter’s oscillating U-tube with full range viscosity correction and reference oscillator allows long term calibration stability and measurements at all temperatures with a single calibration.
cGMP/GLP Calibration
Calibrate the DDM 2911 with 2 or 3 NIST 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. 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.
Computer Windows Based Flexibility
32 gigabytes of internal memory allow almost unlimited capacity for saving measurement data. The DDM 2911 Density Meter 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’s 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’s internal memory
Copy methods, transfer concentration tables, download data, etc., via the USB ports which are conveniently located on front of unit.
Five total USB ports allow for quick and easy connection to a mouse, keyboard, printer, bar code scanner, or memory stick.
Pharmaceutical Lab Density Meter with Versatile Communication Capability
The DDM 2911’s standard communication package includes:
Ethernet Port for Network Cable Connection
5 USB ports
2 RS 232 Ports
Allowing capability to:
Export measurement results to a thumb drive, store it locally on the C:\ drive, or easily send data to any external PC, LIMS, etc.
Print measurement results to a local or networked printer. Use any printer; just load the proper printer driver as you would with any PC.
Save measurement data direct to your Network/Server
cGMP/GLP Printing for your is a must for your Pharmaceutical Density Meter
Sample measurement reports are edited quickly and easily. Just import your logo to the DDM 2911 Density Meter. You may also print your company’s customized “C of A” directly from the Density Meter.
NIST Traceable Calibration Standards
Rudolph knows how important it is to calibrate with Traceable Standards. Therefore, we include either a NIST or UKAS standard in the accessories provided with all of our density meters. The DDM 2911 standard accessories include:
