Abstract
A device for measuring permeability of a filter cartridge seal includes a blocking member for blocking an input to the filter cartridge and a housing for tightening the seal. A removable chamber wall is configured to form a sealed chamber with the housing and the blocking member. Pressure in the sealed chamber is varied to test the seal and to detect leaks.
Claims7
A method for measuring the impermeability of a filter cartridge comprising a casing having an input and an output and having a gasket seal coupled to the casing, with a measuring device comprising a housing and a cartridge receiving means configured to cooperate with the gasket seal of the cartridge, the method comprising:
- disposing a pressure sensitive film on the receiving means of the housing;
- positioning the cartridge in the measuring device such that the gasket seal of the cartridge cooperates with the receiving means of the measuring device housing to form a connection between the measuring device and the filter cartridge, and the pressure sensitive film is positioned between the gasket seal and the receiving means;
- blocking an input or an output of the filter cartridge;
- forming a sealed chamber proximate the input or output;
- varying a pressure in the sealed chamber;
- and
- measuring a change in pressure of the sealed chamber over time to determine the impermeability of the filter cartridge.
