  • APPARATUS FOR TESTING A FILTER
    Publication number: 20170343461
    Abstract: A preferred form of the invention is directed to a system and method used to test filters. The system preferably includes a base unit and a probe operably associated with the base unit. The probe is configured to be deployed adjacent the filter being tested while the filter is located in an operating position. The probe is further configured to allow an operator to vary the mode of operation of the base unit from the probe. The system is configured to automatically exhaust any residual test sample from the base unit and the probe when the system changes between testing a sample upstream and downstream of the filter. The system further includes noise suppression on at least one of the upstream test sample and downstream test sample. The system further is configured to detect when the probe is connected to the base unit.
