Atmospheric Swell Meter
It is a simple measuring device mainly used to detect the expansion change of shale under normal temperature and pressure, so as to evaluate the inhibition characteristics of various treatment agents on shale. The np-01a expansion meter device compacts the shale powder, puts the treatment agent into the liquid cup, pushes the piston after the shale expands, and finally reads the expansion directly by the digital display. The digital expansion tester is easy to operate and reduces the error caused by manual reading to a certain extent.
