| description | A portable air pressure decay test apparatus for leak testing of a sealed system includes a hollow housing, an air pump having an inlet and an outlet disposed in the housing, and a controller disposed in the housing and connected to the pump for controlling the operation of the pump. A test head is mounted on the housing for releasably attaching to an attachment point of a sealed system. The test head is in fluid communication with the outlet of the pump. When the test head is attached to the attachment point of the sealed system, the controller operates the pump to provide pressured air to the sealed system and raise the pressure in the sealed system to a predetermined value. After the predetermined value of pressure is reached, the controller stops the pump and monitors the air pressure in the sealed system for a predetermined time interval to measure an air pressure decay rate. The controller then compares the measured air pressure decay rate with a predetermined air pressure decay rate to indicate if a leak rate of the sealed system is acceptable. The apparatus preferably includes a power source connected to the pump and the controller disposed in the housing. The power source is preferably a removable battery or the like. |
