1 to 100 kHz/20-200A AC Current Probe for Measuring Inverter Equipment and Other Low Frequency Devices



Hioki current sensors are best-in-class devices for use with power meters, Memory HiCorders and high performance oscilloscopes. The 9272-10 is a 1 to 100 kHz AC current sensor ideal for measuring low frequency equipment such as inverters CLAMP ON SENSOR  9272-10

9272-10 20/200 A AC

This product cannot be used alone. The optional 9555-10 is required in order to supply power and connect the clamp to a Memory HiCorder or other instrument. The clamp can be directly connected with Power Meter 3193-10, and 3390.


Key Features

• Superior low frequency and phase characteristics suitable for testing the current and power of inverter control devices

• Wide 1 Hz to 100 kHz frequency bandwidth perfect for harmonic analysis, FFT analysis and waveform monitoring
