Hioki 9018-50 Clamp On Probe for High-Accuracy AC Current Measurement
The Hioki 9018-50 Clamp On Probe is designed for professionals and engineers who require precise AC current measurement on live lines without interrupting power flow. Its multi-range capability allows measurements from small to large currents, making it versatile for industrial, laboratory, and field applications.
Superior Phase and Waveform Accuracy
Unlike standard clamp probes, the 9018-50 delivers high-accuracy phase characteristics, which ensures faithful waveform capture. This is particularly important for analyzing harmonics or transient events such as motor rush currents. By providing accurate phase and amplitude measurements, this probe enables reliable waveform analysis when connected to DMMs or Memory HiCorders.
Wide Application and Ease of Use
This probe features six selectable ranges for currents up to 500 A AC and outputs a voltage signal via a BNC terminal. It is safe for use on 50/60 Hz commercial power lines with a CAT III 600 V rating, and no external power supply is needed, making setup quick and convenient. Its compact design allows it to fit around medium-sized conductors while maintaining wide-band response, essential for capturing inrush currents during motor start-up.
Motor Inrush Current Measurement
The 9018-50 excels in capturing transient events such as motor power-on inrush currents. When paired with Memory HiCorders or a waveform recorder, engineers can analyze current surges accurately, supporting maintenance, troubleshooting, and energy efficiency evaluation.
With its combination of safety, precision, and ease of use, the Hioki 9018-50 Clamp On Probe is a reliable tool for capturing AC current waveforms across a wide range of applications.
