With set vibration times and time two measurement methods, The design accord with human body engineering, the operation is simple. Meet specification requirements of USP (the United States pharmacopoeia), BP (British pharmacopoeia) and EP (European pharmacopoeia) and GB/T 5162-5162 / ISO3953:1993 (metal powder the determination of tap density),
二、应用范围:Scope of application
适用于非金属粉、金属粉体、制药、化工、电池、磨料以及科研教学等领域,
It is suitable for non-metallic powder, metal powder, pharmaceutical, chemical, battery, abrasive and research teaching etc field ,
Powder cylinder fixed in the mechanical vibration device, mechanical vibration device vibrate under driven by vibrating motor, the calibration test tubes which containing powder vibrate with the mechanical vibration device, with the increase of vibration frequency, the powder in the measuring cylinder gradually compact by vibration, When vibration frequency reaching setting the number of times, mechanical vibration device will stop the vibration, Read the volume of the calibration test tube, according to the definition of density: mass divided by volume, thus find out the powder density after compaction.
