一、Overview          

       This instrument refers to a water loss measuring instrument with a pressure difference of 0.69MPa. It is mainly used to determine the amount of water loss of drilling fluid and obtain the filter cake formed after water loss. It is widely used in major oil fields, geological exploration and laboratory drilling fluid analysis and determination.
