Rohmann ELOTEST M2 V3 universeel wervelstroomapparaat voor oppervlakte scheurdetectie

De ELOTEST M2 V3 is geschikt voor alle soorten inspecties van hoogfrequente scheurdetectie op hooggelegeerde componenten tot middenfrequente scheur- en corrosietests laagfrequente testen van meerlaagse structuren voor stress scheuren.

Het dockingstation verandert het draagbare apparaat in een bench-top instrument met de connector voor pc of printer. Door het simpelweg aan te sluiten, wordt de intelligente laderelektronica geactiveerd en houdt het batterijpakket dat erin is geïntegreerd
het instrument op zijn optimale belastingsniveau.
