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.
