Abstract: The disclosure describes a filter test device which may be incorporated in a filter testing arrangement that tests the integrity of one of sev- eral filter systems according to one of several sets of parameters, each set of parameters corresponding to a respective filter system. The testing arrange- ment includes a source of pressurized gas and the filter system includes a filter vessel containing at least one filter element between an inlet and an outlet. The filter testing device comprises an inlet which communicates with the gas source, an outlet which communicates with inlet of the filter ves- sel, and a pneumatic valve apparatus disposed between the inlet and the outlet of the filter test device for regulating the flow of gas from the source to the filter vessel. The filter testing device also com- prises an electronic controller for controlling the pneumatic valve apparatus in accordance with one of the sets of parameters. This electronic controller includes a memory circuit for storing all of the sets of parameters. The filter test device further com- prises a mechanism for selecting the one set of para- meters from all the sets of parameters stored in the memory circuit. In this manner, the electronic con- troller may control the valve apparatus in accordance with the set of parameters corresponding to the one filter system.
