How to Measure the Tapped Density and Calculate the Compressibility with The PowderPro A1

Tapped Density(ρT): The tapped density of a powder material is determined by the volume and mass occupied by the packed powder after it has been tapped for a defined period of time. ρT=M/VT

Compressibility(Cp): Compressibility is a calculation of a powder’s unit volume change after applying pressure. Cp=100(ρT−ρBT)

In this video, Shelly Zhang from Bettersize instrument teaches you how to measure the tapped density using fix volumetric method and calculate the compressibility of powder materials with automatic powder characteristics tester: PowderPro A1. This instrument not only capable of accurately measuring the characteristics of powder materials but also the Bettersize app provides one-click calculations and results and saves your time.
