With an infinite, variable range of voltage settings, this shoulder type detector maintains a steady inspection rate on any setting from 1,000 to 15,000 volts. This wide range permits inspection of coal tars, extruded and tape coatings , as well as thin film coatings. Pulse voltage output only.
Models 915 and 925 incorporate all of the features and capabilities of the corresponding Model 715 and 725 detectors. Shoulder models with flat brass brush electrodes are especially suited for "spark testing" coatings on tanks and flat surfaces.
