The instrument is used to determine the water loss of drilling slurry when it goes through a certain size of filtration area within a certain time (30 minute) under stipulated working pressure (0.69 MPa). The instrument has two types, with an inflator, or with a decompression device. The instrument with an inflator can provide air source using the inflator equipped, so it is simple to be operated and convenient to be carried. It is the best choice of the similar instruments.
