Hioki 9010-50 Clamp On Probe for Accurate AC Current Waveform Measurement
The Hioki 9010-50 Clamp On Probe delivers reliable and economical AC current measurement for a wide range of industrial, laboratory, and field applications. Designed for live power lines, this clamp sensor eliminates the need to cut wires, making current measurement safer and more convenient. It is perfectly suited for waveform recording with DMMs and Memory HiCorders, offering multi-range flexibility for precise monitoring.
Economical and High-Precision Measurement
With six selectable ranges covering 10 A to 500 A AC, the 9010-50 allows users to measure both small and large currents accurately. The probe outputs a 0.2 V AC full-scale signal that can be easily connected to voltage input devices with a high input impedance of 1 MΩ or higher. Its CAT III 600 V rating ensures safe operation on commercial power lines without requiring an external power supply.
Accuracy and Frequency Performance
The 9010-50 provides ±2 % reading ±1 % full-scale accuracy for standard 45–66 Hz signals. For higher frequencies (40 Hz–1 kHz), the accuracy is slightly range-dependent: ±6 % reading for 10 A and 20 A ranges, and ±3 % reading for 50 A and higher ranges. This ensures reliable waveform capture across various applications, from small laboratory setups to industrial power monitoring.
Compact and User-Friendly Design
Featuring a core diameter of φ46 mm, the probe easily accommodates medium-sized conductors. Its compact form factor (78 × 188 × 35 mm, 420 g) and 3 m cord length make it ideal for both benchtop and portable setups. The BNC output terminal allows straightforward connectivity to recording and measurement devices.
By combining precision, flexibility, and cost-effectiveness, the Hioki 9010-50 Clamp On Probe is a dependable tool for capturing AC current waveforms in a variety of environments.
