A pressure testing apparatus has a probe with a piercing tip. The probe sealingly engages a special entry port having a mating pressure-coupling body which establishes a sealing connection with the probe before the tip pierces the package. An adhesive sheet flange extends about the body of the entry port and sealingly secures the body to the package. This eliminates the need for external clamping or holding fixtures. In a preferred embodiment the pressure-coupling body is formed of a semi-rigid material and has a tapered through bore for receiving the probe. A face of the body defines a stop which limits the piercing travel of the probe tip. The probe assembly, in one embodiment has inlet and return ports which accommodate a pressure supply inlet line and a pressure sensing return line, respectively. A single piercing tip enters the packaging, with the inlet port located near to the tip end of the probe, and the return port located at a distal end. The interior of the probe thus serves as a pressure buffer chamber, enhancing the stable performance of a microprocessor-polled pressure sensing unit, and preventing obstruction of the return port or of the sensor by package debris. A pressure supplying and sensing system is shown, which operates at positive or negative pressures.
