CWT Rogowski Current Probes

Industry-Leading Flexible, Clip-Around, Wideband Rogowski Oscilloscope Current Probes for High-Frequency Measurement

The CWT range is a versatile family of wideband current probes based on Rogowski coil technology, offering exceptional frequency response from 0.008Hz to 50MHz and designed for measuring peak currents from 30A to over 300kA. Select models—including the CWTLF, CWTHF, CWTMini50HF, and the latest CWTUMHF-F feature our patented electrostatic shielding technology, delivering unmatched noise immunity and exceptional measurement accuracy even in electrically noisy environments where conventional probes fail. This proprietary shielding ensures reliable performance across the entire 0.008Hz to 50MHz frequency spectrum.

Use the selection filters below to identify the optimal CWT probe for your application—quickly and efficiently. If your technical specifications exceed our standard configurations, our engineering team is ready to support you with a purpose-built measurement solution.
