High Precision DC to 100 kHz/500A AC/DC Pull-through
Current Sensor with ±0.05% Basic Accuracy
Exclusive Academic Offer

Hioki pass-through AC/DC current sensors are best-in-class devices for use with power meters, Memory HiCorders and high performance oscilloscopes. The 9709 is a DC to 100kHz/500A sensor, ideal for capturing current signals from switching power supplies, inverters, power conditioners, etc.

CAT III 1000 V

Key Features
• Super high precision, ±0.05% amplitude accuracy, ±0.2° phase accuracy
• DC to 100 kHz bandwidths with excellent frequency characteristics
• Ideal for evaluation of solar power generation and fuel cells to measure battery charge and discharge and the secondary side of inverters
• For observing waveforms to be used with the oscilloscopes or Memory HiCorders (use with SENSOR UNIT)
