Summary
  This instrument is designed and made as per GB/T 4985-2010 Standard Penetration Test for Petroleum Waxes. It is used to determine the penetration of petroleum waxes. It can also be used to determine solid fine particle, powder, colloid and raw-food materials such as cheese, glycine, butter, cream and leavening. It can be widely used in food industry, highway engineering and other industrial fields.
