About PMK IWATSU

IWATSU Test Instruments Europe GmbH (brand PMK IWATSU) is a family-owned manufacturer of electrical measurement and test equipment based in Bad Soden am Taunus. PMK develops and manufactures high-frequency probe solutions for electronic test and measurement technology, including optically isolated high-voltage probes, differential high-voltage probes, current clamps and current shunts. The portfolio is complemented by IWATSU measuring instruments: curve tracers for the characterization of power semiconductors (IGBT, MOSFET, SiC, GaN), BH analyzers for soft magnetic materials, and digital oscilloscopes of the DS-8000 series. The Cleverscope brand provides galvanically isolated oscilloscopes for measurements in power electronics switching bridges. In addition to standard products, the company develops custom solutions and offers service, repair and calibration of probes and measurement channels. Customers come from power electronics, semiconductor characterization, automated test systems, and research and development; sales and service locations exist in Germany, the United Kingdom, the USA, Japan and New Zealand.
