Accurate Density Determination of Powders and Porous Materials

For accurate determination of the volume and skeleton density of powders, granulates, porous materials, mixtures, pastes and liquids,Microtrac’s新BELPYCNO L是首选。这种气体密度计取代了传统的液体置换法。

The combination of an internal temperature control and an absolute pressure transducer compensates any influences from ambient temperature and pressure fluctuations. The expansion path of the Helium gas from the reference into the sample chamber avoids any contamination issues.

Benefits include:
• Built-in linearised absolute pressure transducer
• Sample cell and reference volumes are separated from the electronics
• Built-in accurate ATC (Automatic Temperature Control)
• Short measurement time and fast system stabilisation
• Rugged design - suitable for harsh industrial environments

In the BELPYCNO L a probe gas, such as Helium, is used which can reach even the smallest pores with a diameter of less than one nanometer. Thus, the density of powders and porous materials can be determined exactly.
