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.
Model 9272-10 cannot be used alone. The 9555-10 Sensor Unit must be used when connecting the probe with a Hioki Memory HiCorder. Model 9272-10 can be connected directly to Models 3193, 3194 and 3390 power measuring devices.
Superb low frequency and phase characteristics suitable for testing the current and power of inverter control devices
• Wide 1Hz to 100kHz frequency bandwidth perfect for harmonic analysis, FFT analysis and waveform monitoring
• Measure current with low frequencies such as inverter control devices
