Abstract
A device for detecting stray electrical currents in fluid mediums comprises at least two probes for partially disposing in a fluid medium and a control unit. The control unit comprises at least one analog-to-digital signal converter in electrical communication with at least one of the probes, at least one audio-visual alarm, and a processor operably coupled to the at least one converter and to the at least one audio-visual alarm. The processor is operable to measure an electrical potential difference between the two probes, to calculate at least one frequency-dependent characteristic associated with a plurality of said measurements, and to transmit an alert signal if the at least one frequency-dependent characteristic satisfied a threshold. Advantageously, by monitoring for the frequency, the device more consistently and more reliably detects the presence of stray alternating currents.
