Abstract

The invention relates to a device for carrying out integrity tests on filter elements by means of test gases, comprising a device housing (3), with an electronic controller (4), arranged therein for regulation and control of the progress of a test programme for filter elements, a filter housing (6), for housing a filter element (2) under test, a pneumatic unit (5), connected to the controller (4) and the filter housing (6), in particular for the generation and measurement of gas pressures, an electronic memory unit (10), which may be connected to the filter element (2) under test and a communication unit (13′), connected to the controller (4), for the exchange of data between the controller (4) and the electronic memory element (10). The communication unit (13′) is preferably embodied as an antenna (14′) and the electronic memory element (10) as a transponder (11). In addition to the device a method for carrying out integrity tests and a computer programme product are also disclosed.
