A system and method for allowing network users to securely administer and deploy network nodes. The syringe includes a tubular plunger slidably received in the hollow interior of the tubular cartridge. At least one element is applied on a second form element. In addition, the assembly includes a second bladder that is provided to receive effluent from the fuel cell such as carbon dioxide and unreacted fuel and water from the anode side, and water from the cathode side, or a combination of both. The body can be an astragal, a vertical frame member, or the like. The instrument embodies a four-point ohmmeter circuit measuring Hall Effect sensor resistance and tracking the effect of temperature on the Hall Effect sensor.
