Rudolph Digital Density Meters (Densitometer) provide Full 21CFR Part 11 Instrument Level Compliance

The DDM 2910 Density Meter’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 2910’s 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.

cGMP/GLP Calibration

Calibrate the DDM 2910 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. 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.

Windows Computer Based Flexibility

32 gigabytes of internal memory allow almost unlimited capacity for saving measurement data.
The DDM 2910 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 2910’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 2910’s internal memory
Copy methods, transfer concentration tables, download data, etc., via 2 of the 5 total USB ports which are conveniently located on front of unit.
Four total USB ports allow for quick and easy connection to a mouse, keyboard, printer, bar code scanner, or memory stick.

Versatile Communication Capability

The DDM 2910’s standard communication package includes:

Cat 5 Network Cable Connection
5 available USB ports (2 Front, 3 Rear)
2 RS 232 Ports

Allowing the Density Meter (Densitometer) to directly:

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

Sample measurement reports are edited quickly and easily. Just import templates from Word® or Excel® to the DDM 2910 Density Meter and print your company’s customized Dertificate of Analysis directly.
