Surface wettability measurement device at low pressure

This device is a modified version of the old and previous models and has made it easier to test and measure better. Fill the device with the desired fluid (for example, in petroleum engineering: in the process of drinking salt water in the process of draining oil) and then fill the rock saturated with fluid (oil in the drinking process, salt water in the draining process) in it. we put. Then open the cap valve and install the cap on the device. After draining the excess fluid, I close the valve and start the test.
