Liquid density CRMs characterization system

The DRM is a hydrostatic weighing apparatus for characterization of liquid density certified reference material (CRM) that is critical for the calibration of densimeters.

The liquid density is traced to the SI units of length and mass.

KEY FEATURES

· Density can be measured at specified temperature

· A solid reference sphere or ring traceable to national standards

· Automatic calculation of the measuring result

· Ambitious conditions are included in the algorithm

SPECIFICATIONS

· Temperature: +15 to +180°C, optional extended temperature available

· Stability: ± 0.005 K

· Uniformity: < 0.005 K

· Solid reference: silicone sphere

· Vibration isolation module and ambition chamber are available as options
