Suragus EddyCus® lab 2020SR – Non-contact Single Point Sheet Resistance Tester. A non-contact single point sheet resistance measurement system. The device contains an eddy current sensor set that induces weak currents into conductive films and material. The induced currents in the specimen generate an electromagnetic field that correlates with the sheet resistance of the measure object. https://www.environmental-expert.com/downloads/eddycus-tf-lab-brochure-378126.
