Ideal for Measuring AC Current with Low Frequencies such as Inverter Control Devices
CLAMP ON SENSOR 9272-05
Description
Hioki current sensors are best-in-class devices for use with power meters, Memory HiCorders and high performance oscilloscopes.
The 99272-05 is a 1Hz to 100 kHz AC current sensor ideal for measuring low frequency equipment such as inverters.
CAT III 600V
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 (AC only)
