The DEFECTOMETER 2.837 is a portable battery operated eddy current instrument that is used for detecting surface flaws in conductive materials (metals). The material surface may be painted, lacquered or untreated. In additon, the instrument can be used for simple materials sorting applications, for example, to differentiate between heat-treated and unheat-treated components. The DEFECTOMETER's high sensitivity, easy operation, and low price makes it an ideal general purpose instrument for maintenance inspection and metal processing and manufacturing facilities..
