DDM 2911 PLUS Density Meters
Manufacturer: Rudolph Research Analytical
SKU: Inquire
Description
Rudolph Research Analytical's DDM 2911 PLUS is a benchtop digital density meter designed for high-precision measurements. It determines sample density with a resolution of 0.000001 g/cm³. Temperature is controlled by a Peltier system across a range of 0°C to 100°C, with a resolution of 0.001°C. The instrument requires a sample volume of approximately 1 milliliter, though this can depend on the selected loading technique. Results can be displayed in multiple units, including g/cm³, kg/m³, specific gravity, and degrees Baumé or API. It is suited for applications demanding rigorous quality control and compliance with standards. Features may encompass statistical analysis of multiple measurement cycles for GLP/GMP documentation, support for electronic records and signatures per 21 CFR Part 11, and specialized functions like a video bubble detection system for beverage analysis. Common uses include petroleum testing (e.g., API gravity determination), concentration analysis in chemicals, raw material verification in pharmaceuticals, and quality assurance in the beverage industry.
