Abstract
A hand held wand utilizes an elongated rigid hollow longitudinally extending stainless steel tube open at both ends. A data collection probe is disposed in one tube end. A data uploading port is disposed in the other tube end. The probe and port each include a stainless steel body electrically and mechanically engaging the tube. Each body has a front surface disposed outside of the tube with a peripheral annular ring and a central recess extending inwardly and terminating in a rear surface having a first opening. Each body also includes a corresponding longitudinally extending central electrode disposed in the corresponding recess. Each central electrode has an exposed front surface flush with the ring and a rear surface aligned with and spaced from the opening. Electrical insulation is disposed in the recess to electrically isolate the electrode from the body and the tube. The two bodies and the tube define a common external electrical ground with respect to the central electrodes.
