Abstract: A device, and corresponding method, for determining a material composition of the pipe includes a probe, a resonance frequency measurement circuit, and a material analyzer. The probe includes an oscillator circuit and can be inserted into an interior cavity of the type. The probe also can emit electromagnetic radiation into the interior cavity via the oscillator circuit. The frequency measurement circuit is in operative communication with the oscillator circuit and is configured to output resonant frequency measurement data indicative of a resonance frequency of the oscillator circuit when inserted into the interior cavity. The material analyzer can receive the resonance frequency measurement data, and an additional measurement, and can output an indication of material composition of the pipe based on the resonance frequency measurement data and the additional measurement.

Abstract: A device, and corresponding method, for determining a presence of lead in a material composition of a pipe includes a probe, a resonant frequency measurement circuit, and a material analyzer. The probe includes an oscillator circuit and can be inserted into an interior cavity of the pipe and emit electromagnetic radiation. The frequency measurement circuit operatively communicates with the oscillator circuit and outputs resonant electromagnetic frequency measurement data indicating a resonant electromagnetic frequency of the oscillator circuit. The material analyzer receives the resonant electromagnetic frequency measurement data, and an additional measurement selected from the group consisting of (i) a measurement of power dissipation of the oscillator circuit and (ii) an interior diameter of the pipe, and outputs a positive or negative indication of whether lead is present in the material composition based on the resonant electromagnetic frequency measurement data and the additional measurement.
