The VM-810 operates at 83.1kHz which is ideal for water and gas utilities which generally are larger pipes with bell housings and gaskets. The VM-810’s higher frequency is also good for locating ungrounded small diameter drop wires and inducing signals through the soil, onto services when direct connecting is not an option.
For thicker coatings such as coal tars, extruded and tape coatings, the Model 785 has a range of infinite voltage settings from 1,000 to 15,000 volts. This wide range permits you to maintain a steady inspection rate on most types of coatings on most pipe sizes without changing detectors. Pulse voltage output only.
