Product overview
Density Meter (ASTM D4052) determines liquid specific gravity and API gravity using oscillating U-tube technology.
The DDM 2911 Laboratory Density Meter is a perfect choice for a pharmaceutical density meter or any lab where high accuracy is required. The 2911 is one of the most capable instruments in the Rudolph DDM series density meter line, offering a wide measurement range, high accuracy, and the on-board range methods and electronic data tracking required in the most demanding laboratories in the world.
For laboratories requiring high performance with an entry-level or intermediate configuration, options like the DDM2909 density meter are also widely utilized. For applications that require rapid field testing alongside benchtop analysis, combining these static instruments with a handheld density meter provides a complete operational workflow.
Designed for the most demanding cGLP/GMP Laboratories, the DDM 2911 Density Meter offers density accuracy to 0.00005 g/cm³. If you work in the Pharmaceutical, Chemical, Beverage, Fragrance, or Petroleum industries and need the highest level of accuracy, the DDM 2911 is a perfect choice for your lab. Rudolph is a longtime participant in ASTM Petroleum Testing and Proficiency Testing Programs. To secure these precise instruments with full support, partnering with a premier Density meter supplier in the UAE. guarantees access to certified installation, calibration, and long-term technical service.
