Description
Hioki 3273-50 Clamp Probe for Accurate Low-Current Waveform Capture
The Hioki 3273-50 Clamp On Probe is engineered for engineers and researchers who need precise current measurement across a broad range, from 10 mA to 30 A. With a flat bandwidth of DC to 50 MHz, it accurately captures both transient and steady-state currents. It is ideal for applications in switching power supplies, inverters, and motor controllers where observing high-fidelity waveforms is essential.
Advanced Measurement Technology
Hioki employs the zero-flux method and proprietary thin-film Hall elements to deliver exceptional performance. The Hall element detection efficiently captures low-frequency currents including DC, while the zero-flux method ensures high accuracy and minimal insertion impedance. This combination provides a high S/N ratio across a wide frequency range, making the probe suitable for detailed waveform analysis and electronic circuit design verification.
Ease of Use and Safety
The probe connects directly to oscilloscopes or Memory HiCorders via a BNC terminal. Its high-permeability magnetic shield reduces interference from nearby high-current lines, ensuring accurate low-current measurements. For continuous measurements or when power is unavailable from the instrument, the optional Power Supply 3269/3272 provides stable operation. Users can easily handle and connect the probe thanks to its ergonomic design and robust construction.
Ideal Applications
The 3273-50 is suited for laboratory and field use, enabling engineers to measure transient currents, observe inrush currents, and verify high-speed signal circuits without compromising accuracy. Its combination of wide bandwidth, high S/N ratio, and advanced Hall element technology ensures clear, reliable measurements under diverse conditions.
