Bubble Point Tester

A bubble point tester is a system designed to test the filters applied in the oil and petrochemical industry.


The procedure of a bubble point test is as follows: A controlled flow of gas is applied to one side of a wetted filter, with the tubing downstream of the filter submerged in a bucket of water. The exact amount of transferred air volume and the outcome pressure is measured. The first bubble point of filter quality appears and welding sections and aperture diameter of filter media is tested and finally the results will be reported to study.
