Abstract

Den foreliggende oppfinnelsen vedrører en testinnretning for å detektere og lokalisere materialinhimogeniteter i elektrisk ledende prøver (10), omfattende en holder (30) for prøven som skal testes, en temperaturinnstillingsinnretning (30, 50, 60) for dannelse av en temperaturprofil i prøven (10), en drivinnretning for posisjonsendring av prøven (10) forbundet med holderen (30), og minst en måleverdiopptaker (20) for kontaktløs måling av magnetfeltet utenfor prøven (10).
