DDM 2909 Automatic Density Meter by Rudolph Research Analytical
The Rudolph DDM 2909 Automatic Density Meter features built-in Peltier Temperature Control of the Sample, Full Range Viscosity Correction, Reference Oscillator and VideoViewTM for easy bubble detection, and is fully GMP/GLP Compliant. With the flexibility of Windows the DDM 2909 is Network ready with Internet connectivity allowing remote access to Rudolph Research Analytical’s Service and Technical Support Team.
The 2909 comes complete with 20 Density to concentration tables which include Brix, Alcohol, API, and many various laboratory reagents. An unlimited number of additional tables, polynomials, and formulas may be added.
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 Meter measurement applications, create a sample method using 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:
- Baumé of Hydrochloric Acid
- Normality of Sulfuric Acid
- Density of Gases and Aerosols
- Drug to Propellant Ratio
- Lead Content
- ppm Gold in Acid
- % Toluene in Heptane
- Fat in Lubricant
- Mole Fraction of Methanol
- % HNO3
- Monomer Solutions
- Potassium Permanganate
- Hydrogen Peroxide
- Molar Solutions of EDTA
- SG of Urine
- Sodium Hydroxide
Setting up your custom method on your Density Meter is as simple as filling out a few screens like the one below:
Full Feature VideoView™
VideoView™ provides superior high resolution visual bubble detection within your samples with live on-screen video viewing. Rudolph’s industry leading 10X magnification aids in identifying bubbles if present in the sample.
The video clarity, magnification, and resolution mean no more straining to see small difficult-to-detect air bubbles in your sample. Rudolph’s exclusive VideoView™ is protected under Patent #7,437,909.
Oscillating U-Tube with Viscosity Correction and Reference Oscillator
The DDM 2909 Density Meter’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.
