HIOKI Transducers / Pass-through sensors

CT6904_Pass-through-current-sensors-2-1

High-Accuracy AC/DC Current Measurement up to 2000 A

HIOKI high-accuracy transducers are designed for precise AC and DC current measurements in demanding test environments. Depending on the model, they support currents from tens of amperes up to 2000 A, bandwidths from DC to 10 MHz, and accuracy down to ±0.025 % rdg., enabling reliable measurement of both fast current dynamics with outstanding repeatability. 

HIOKI pass-through sensors are used in applications where high current, accuracy, and low phase error are critical, including power measurement, power electronics testing, and efficiency analysis. Typical applications include inverter and converter testing, EV system development and harmonic analysis in R&D and industrial environments.
