A manifold assembly for a portable leak tester includes a manifold housing defining a fluid inlet, a fluid outlet, a pressure port, and a fluid passage. The fluid passage connects the fluid inlet, the pressure port, and the fluid outlet in fluid communication. A supply control valve is mounted to the manifold housing. The supply control valve is operable to open and close fluid communication through the fluid passage, between the fluid inlet and the fluid outlet. A pressure transducer is coupled to the pressure port. The pressure transducer is operable to sense a fluid pressure in the fluid passage. A manifold controller is mounted to and supported by the manifold housing, and is in communication with the supply control valve and the pressure transducer. The manifold controller includes all software and hardware necessary to control the supply control valve, the pressure transducer, and to communicate with a testing controller. |
