HIOKI Precision Current Clamps with Zero-Flux Technology

HIOKI-Current-clamps-2-1

Accurate current measurement with flexible clamp-on design

HIOKI precision current clamps enable accurate, non-intrusive AC and DC current measurement without interrupting the circuit. Across the portfolio, they support currents from milliampere levels up to 1000 A, bandwidths up to 2 MHz, and high measurement accuracy. Select the optimum current clamp for your application, for example the CT6746A Current Clamp for currents up to 1000 A or the CT6834 with an ultra-slim design for measurements in confined areas. All models are suitable for measurements on production-ready equipment in operation.

Precision current clamps are used where accuracy, ease of use, and minimal impact on the test setup are essential, including vehicle on-board measurements (incl. WLTP), power electronics testing, efficiency analysis, and measurements in hard-to-access environments.
