AC/DC CURRENT PROBE
CT6841-05

Consistent, High-precision Current Testing Across a
Wide Temperature Range
Exclusive Academic Offer

Hioki AC/DC clamp sensors are best-in-class current sensors for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6841 is DC to 1 MHz/20 A sensors, ideal for capturing signals during the efficiency testing of batteries, inverters and power conditioners.

Key Features
• Ideal for use in environmental testing with broad -40˚C to 85˚C temperature range
• High precision with a clamp-type design, ±0.3% amplitude accuracy, ±0.1° phase accuracy
• Wide-bandwidth DC to 1 MHz
• Single-handed operation and robust locking mechanism
• Reduced effects from magnetic fields, conductor position, and noise from nearby wires
• For EV/HEV battery charge and discharge efficiency measurement and inverter and power conditioner conversion efficiency evaluation

Model No. (Order Code)

CT6841 20 A AC/DC, PL23 terminal
CT6841-05 20 A AC/DC, ME15W terminal

Note: These products cannot be used alone. The optional SENSOR UNIT is required in order to supply power and connect the clamp to a Memory HiCorder or other instrument. Products can be directly connected to the compatible Power Meters and Power Analyzers.

High-accuracy current sensors ideal for use with oscilloscopes and power meters

Compared to current sensors that use Hall elements, flux gate type current sensors are not prone to measurement error caused by variations in the external temperature. In addition, they can measure extremely low input (current values) and current waveforms with phase that lags by 90° with a high degree of precision. The CT6840 Series AC/DC Current Probes are ideal for measuring power waveforms with a digital oscilloscope and power meters.
