How to Choose A Density Meter for your Application.

How to select an Automatic Density Meter model for chemical, pharmaceutical, petroleum, cosmetics, essential oils, petrol-chemical, education, and university applications. The Rudolph DDM2910 and DDM2911 offer a wide range of features. These include, sample handling, sample loading, method management, measurement, and measurement fail-safe options. Rudolph Density Meters address each aspect of the density measurement process to ease and speed sample handling, manage measurement methods, and monitor the density meter’s testing environment. In addition, user friendly features 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. Offering one of the widest temperature control ranges in the industry, giving you the correct temperature for your measurement application.

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. Rudolph, helps the user avoid error causing air bubbles, a common cause of poor results.

Automatic Density Meters with 21CFR Part 11 Instrument Level Compliance

The DDM2910 and DDM2911’s 21CFR Part 11 software module is easily enabled through the user friendly, digital touch screen. This module gives you full compliance with 21CFR Part 11.

Oscillating U-Tube with Viscosity Correction and Reference Oscillator (Patent #US7735353B2)

The Rudolph Research Density Meter’s oscillating U-tube with full range viscosity correction and reference oscillator (Patent #US7735353B2 ). This technology allows for long term calibration stability and measurement at all temperatures with a single calibration.

cGMP/GLP 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 are possible.

Computer Windows Based Flexibility

32 gigabytes of internal memory allow almost unlimited capacity for saving measurement data. The DDM 2911 and DDM 2910 Density Meters are network ready so data may also be saved directly to your server or to any directory.
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 Embedded 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 connections. You may add a mouse, keyboard, printer, bar code scanner, or memory stick.

Versatile Communication Capability

The DDM2910 and DDM2911 standard communication package includes:

Cat 5 Network Cable Connection.
5 USB ports.
2 RS 232 Ports.

cGMP/GLP Printing

Sample measurement reports are quickly and easily edited. Just import templates from Word® or Excel® to the DDM2910 and DDM2911 Density Meter. You may then print your company’s customized Certificate of Analysis directly.

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.

Rudolph offers a wide range of sample handling option

The Rudolph DDM with AutoFill™ was developed by listening to customers who wanted an easier method of sample loading. Customers wanted to decant right from their existing containers. With AutoFill™, samples are easily poured right into the sample well. Users have do not have to come in contact with the sample. Simply pour it in. The lid is closed and the sample is advanced to the U-Tube with the push of a button on the DDM touch screen. To clean, open the lid and pour in the solvent of your choice. Close the sample well lid again, press a button and the solvent is flushed through the U-Tube and air drying is automatically started.

Who Should Use this System?

Users who make many measurements each day and want an easy to load and clean Density Meter.
Laboratories who do not want to come in contact with caustic acids, or bases.

Automatic Density Meters easily integrate with Laboratory Automation Flexibility

Rudolph Research knows you need to save time performing routine measurement tasks. Saving time, save money. 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.
