NVLAP LAB CODE: 200898-0Accreditation to ISO/IEC 17025:2005
United States Department of CommerceNational Institute of Standards and Technology
ApplicationsThe DDM 2910 Density Meter, with high precision Peltiertemperature control of sample, has the featuresto meet the needs of today’s industries.
Flexible Method ManagementFactory installed measurement methods allow forimmediate selection of the correct method to matchthe most common applications.
For unique measurement applications, create a sample methodusing an unlimited number of Concentration Tables, Formulas,and Polynomials to match the measurement methods used inyour laboratory. A few customized sample methods shown below:
• Concentration D2O – Heavy Water • Mole Fraction of Methanol
• Baumé of Hydrochloric Acid • % HNO3
• Normality of Sulfuric Acid • Monomer Solutions
• Density of Gasses and Aerosols • Potassium Permanganate
• Drug to Propellant Ratio • Hydrogen Peroxide
• Lead Content • Molar Solutions of EDTA
• ppm Gold in Acid • SG of Urine
• % Toluene in Heptane • Sweeteners
• Fat in Lubricant • Sodium Hydroxide
Setting up your custom method is as simple as filling out a fewscreens like the one below.

with the Flexibility of Embedded Windows® 7
Computer Embedded Windows 7 Based Flexibility• 8 gigabytes of internal memory allow almost unlimited capacity for savingmeasurement data. The DDM 2910 is network ready and data may also besaved directly to your server or to any directory desired.
• Internet access is possible directly from the DDM 2910’s touch screen. Theembedded Disk Protection feature protects the operating system againstmalware infections in networked environments.
• Embedded Windows 7 based navigation architecture is so intuitive that mostoperators will never read the manual. But should you wish to reference themanual, it is stored right on the DDM 2910’s internal memory.
• Copy methods,transferconcentrationtables, downloaddata, etc., viathe USB ports onthe front of unit.
• Five USB portsallow for quickand easyconnection to amouse, keyboard,printer, bar codescanner,or memory stick.
cGMP/GLP Calibration• Calibrate the DDM 2910 with 2 or 3Traceable Standards – calibrating withmerely air and water appears inconsistentwith cGMP/GLP compliance regulations.
• Can print out complete methodconfiguration, communication settings, aswell as calibration verification andcalibration adjustment data/history.
• Measured values canbe showncontinuously astemperature stabilityis being reached or, atthe discretion of theuser, measured valueswill only be displayedonce the final answeris reached andcompletely stable.
• Unlimited number of customizedcalibration adjustments andcalibration verifications possible.
• Complete History of CalibrationAdjustments and Verifications areavailable to View, Print, and/or Export
• Possible to set calendar reminders asto when Calibrations are due
